Pros:

Non-phthalate PVC

Stays inflated

Slip-resistant

Non-toxic

Included accessories

Cons:

Pump can be defective

UNI FAM is a teensy company with just a few products for sale. Those few products are eclectic though, ranging from hair-care products to exercise equipment. Though their product line may be small, they've still managed to produce an extremely highly-rated set of products. The Exercise Stability Ball Chair has many good qualities going for it, including being slip-resistant, non-toxic, and comes with included accessories.

Non-phthalate PVC
Today's technology has made a seemingly infinite range of products available for purchase. There are endless ways to create new items; however, among those endless ways, sometimes we can't be sure about exactly what chemicals go into the creation of our products, or if they're harmful or not. Luckily the UNI FAM Exercise Stability Ball Chair freely advertises what it's made of: phthalate-free PVC. Though PVC is a synthetic material, being phthalate-free demonstrates its safety.

Stays inflated longer
It's a common problem with any inflatable product: you have to reinflate it eventually. However, some products deflate faster than others. In order to reduce the hassle that is reinflation, the UNI FAM Exercise Stability Ball Chair is designed to stay fuller longer. The less time you have to waste pumping air into it, the faster you can get back to your workout.

Cost and Value
The UNI FAM Exercise Stability Ball Chair has a mid-to-high range price when compared to other items on this list. As with other similar products, it is non-slip, non-toxic, and comes with a few nifty accessories. However, there isn't much that puts it a cut above the rest. While comparable, this product is ultimately similar to others in its class. You may want to consider purchasing this item if an especially important trait for you is how long it holds its air.

Wacces has three keywords that are most important to their business plan: comfortable, affordable, and versatile. Though their business plan seems simple, only focusing on three words, their business itself is vast. They are one of the leaders in the production of equipment for the fitness industry. If you can think of a sport, training regimen, or physical practice, then Wacces has a product for you. The Wacces Professional Exercise, Stability and Yoga Ball

100% Rubber
Most products on this list are made from some kind of synthetic or PVC material. This is extremely common amongst products such as these, and in the industry in general. However, for the conscious consumer who wants to avoid synthetics and choose a product that is better for the Earth, this usually puts them in a bind. However, the Wacces Professional Exercise, Stability and Yoga Ball has a nifty feature: it is made of 100% all-natural rubber. This is extremely unique, as synthetic is the industry standard.

Ribbed for Stability and Non-slip
A common problem people have with anything spherical is that it is slippery. This doubles for something that you sit on. One of the most embarrassing things is when you fall off your exercise chair, especially when you're in class in front of everyone. To provide you with extra grip and prevent this scenario, the Wacces Professional Exercise, Stability and Yoga Ball is ribbed for grip, so you won't slip.

Cost and Value
This is one of the most expensive products on the list. It doesn't come with many accessories other than the pump, and the color range, while larger than some others, isn't especially expansive. However, the high price comes with higher quality materials. It is less expensive to use cheap synthetic PVC material. If you want to know that your product is made from only the highest quality natural materials, you should be ready to spend some extra money.

Pros:

Cons:

Finish rubs off

This Wisconsin-based company is yet another juggernaut in the fitness industry, with a huge range of products, including compression sleeves, medical cushions, home gym equipment, and resistance bands. Black Mountain Products believes in both continual evolution and improvement as well as incredibly high-standard customer service. The Black Mountain Products Exercise Ball demonstrates this attention to design and innovation; it comes in five colors and is ribbed for traction.

Read more

Five Size Options
Most products similar to this one are available in a few sizes--the most common number to top out at is two or three. However, for the truly custom experience, the Black Mountain Products Exercise Ball comes in no fewer than five sizes. There is a perfect size for every person, no matter their weight or height, and no matter what their intention for use.

Battery-free Pump
Many of the pumps that are included with inflatable products are battery-operated. While on the surface this may seem more convenient, there is one major drawback: if your battery runs out, you are out of luck. You are either stuck blowing it up with good old lungpower, or you have to give up entirely. To avoid this situation, the Black Mountain Products Exercise Ball's included pump is battery-free. It is a foot pump that inflates with a simple stepping action with the foot.

Cost and Value
Because of the range in sizes on this product, there is a range of prices. For the mid-size that is comparable to others on this list, the price is mid-range. For the largest size, which is considerably larger, the price is higher. If you just want a mid-sized product, this one is comparable to others on this list, though not much sets it apart from them other than the battery-free pump. However, if you want a larger size than is standard, this is the only option on the list that has an extra-large size.

Pros:

0.2 cm PVC casing

Cons:

Sometimes ships without included parts

Smarter Life is a Colorado-based company that is dedicated to investing in the very best eco-friendly products for health, fitness, travel, and lifestyle products. The company was founded when they realized that there were very few high-quality lifestyles or fitness products that were not only good for the consumer but good for the environment. It was difficult to locate these products, so all but the most dedicated buyers gave up. SmarterLife stepped in and brought all these great products under one roof. The SmarterLife product has many great qualities, such as its high anti-burst rating, being able to support up to 2000 lbs, and coming in four different sizes.

0.2 cm PVC casing
When you're using a product such as this, you expect it to be round. An unfortunate reality is that items of this genre sometimes lose their shape, even turning ovular in the most extreme cases. You won't have to worry about that with this product's extra-thick casing, which allows it to keep its shape even under the toughest circumstances.

Built-in safety features
This product has several safety features built in. One is the ribbed surface for anti-slip protection. The other is a mechanism where, if punctured, the product will not explode as some other similar items do. Rather, it will slowly deflate, saving you from injury and allowing you to finish your workout.

Cost and Value
This product comes in a range of four sizes, all of which are extremely reasonably priced. The fact that this is one of the only products on our list that has dedicated, built-in safety features makes it a cut above the rest. Overall, its value can't be questioned. If safety is your concern, look no further.

Cons:

Smarterlife Products is based out of Colorado. True to their headquarter state's nature, they are extremely eco-conscious. The company was founded when the owners realized that there was an extreme lack of high-quality fitness products on the market that were also good for the environment. Smarterlife Products focuses heavily on research and design, investigating common designs to seek ways to improve them. The Exercise Ball Chair for Yoga shows this emphasis on design.

Included Stability Ring
One of the great things about products like these is the fact that they force you to constantly maintain balance and pay close attention to your posture. You constantly have to be aware of your body to make sure you don't fall off. However, if you're using the product during mentally demanding activities, you may be distracted and slip off. This can happen if you're using it as a chair or doing a specific kind of workout. However, the included stability ring with this product allows you to get all of the benefits without the worry of fear of slipping off.

Setup Guide and other Videos
For some people, opening up a new product is exciting. However, if there is a setup process, it can get very intimidating very quickly--especially when the product comes with a lot of included accessories, as this one does. Some people may put off using it due to this factor. However, Smarterlife has included a how-to video for both setting up the product itself, as well as the accessories. As a bonus, they also include several workout videos as well to help you get the most out of your purchase.

Cost and Value
Despite having all these additional accessories and being highly rated, this is the second-least-expensive product on the list. If you're on a budget but still want to purchase an item that comes with all the bells and whistles, this product could very well be for you. It can go toe-to-toe with other similar items on the list, with the perk of coming with several excellent accessories. A downside is that the handles on the resistance bands tend to wear out after a while--but that is hardly enough to discourage someone, especially when you consider everything else you get for this great price.

Dual-action Pump
Nowadays most inflatable products come with a pump to help you along in the process, and to spare your lungs a workout. This is convenient and saves you a lot of time and effort. However, once you inflate your product, you're pretty much stuck. If you want to deflate it and take it with you somewhere, you have to uncork it and sit on it, wrestling with it until it deflates. Luckily the included pump with the URBNFit Exercise Ball is dual-action, helping you to both inflate and deflate your ball. Because of this handy feature, you won't have to worry about wrestling around on the floor trying to get the air out.

Two included air stoppers
Sometimes we lose things. It's human nature. However, when the thing you lose is the air stopper to something inflatable, you have a problem. Now, suddenly the item is useless. You either have to hope they sell a replacement part, or just order a completely new one. But no need to worry. The URBNFit Exercise Ball comes with two extra stoppers to help us out when we have our human moments and mislay the original one.

Cost and Value
When compared to other items on this list, this product is one of the least expensive. It comes with several accessories such as a workout guide, a dual-action pump, and two extra stoppers. This product is gym-grade, and can hold its own when compared to any other item on this list. The only possible downside is that it does not have an included stability ring, but for many people that feature is not important. Overall, it is well worth the low price.

They have an open-door policy, and always welcome walk-ins who want to stop by their offices to ask questions about their products, or to troubleshoot solutions. By making themselves so approaching and accessible, they make a huge statement about the quality of their products; if they were cheap or broke easily, they wouldn't want to be so easy to find. This company strives for excellence, as shown in the Trideer Exercise Ball (45-85cm) Extra Thick. This product is extra thick, non-toxic, and is also anti-slip.

30-day No-hassle Returns
To demonstrate just how customer-oriented Trideer is, one of the most notable features about the Trideer Exercise Ball (45-85cm) Extra Thick is the customer service. For any reason, if you find yourself dissatisfied with this product, you can return it within 30 days. This process is simple, streamlined, and painless. They will get you a refund, no questions asked.

19 Colors
Most similar products come with a few color options. At most, you're lucky to be able to choose between five hues, among which are black and gray. Not so with the Trideer Exercise Ball (45-85cm) Extra Thick. This product comes in a rainbow array of nineteen different colors. No matter what your aesthetic preference, this company has the color you're looking for.

Cost and Value
The Trideer Exercise Ball (45-85cm) Extra Thick has a mid-ranged price when compared to other items on this list. Though it may not have as many fancy accessories as other products on this list, the ones it does have aren't to be disregarded. If you want peace of mind knowing that there is an excellent customer service team behind you should anything go wrong with your product, you may want to consider purchasing this item. Peace of mind is worth a lot.

Superior Supplements and Nutrition's goal is to be not only a top brand in the fitness and nutrition industry but also a role model on the international market. Their focus is on creating products that will let their customers find success and results at every level, while also making their customers feel supported and confident in achieving their fitness goals. The Superior Fitness 600lb demonstrates this dedication to accessibility with numerous features, such as the included stability ring and included resistance bands.

Non-Stick
A problem many people experience with exercise equipment is that it gets sticky. The materials are usually synthetic, and the user is usually working up a sweat. This is a recipe for an unpleasant sticking sensation. However, the Superior Fitness 600lb has a non-stick coating that makes it easy to move (due to the fact that it won't adhere to the floor). This feature also prevents unpleasant adherence to your skin.

Cushioned handles
The included resistance bands on this product will give you a boost in your workout regimen. This included accessory also has a perk of its own: cushioned handles. Oftentimes the downside of resistance bands is that they have unpleasant, uncomfortable bite. They dig into your hands, which is distracting as you're working out. The cushioned handles prevent this and give you added comfort.

Cost and Value
This product has a mid-range price when compared to other items on this list. However, it comes with accessories that other products on this list do not have. This includes the stability ring, resistance bands, and non-stick surface. Overall, this product is highly rated when compared to similar items. If you're looking for more than just a basic model, but something that is higher-end and comes with loads of accessories but won't break thank, this could be the product you're looking for.

They produce outdoor and fitness gear, with the goal of inspiring people to live adventurously. The Live Infinitely Exercise Ball exemplifies this belief system by allowing you to take your fitness goals anywhere. This product has several notable features, including the ability to support up to 2200 pounds, the anti-burst design, and the wide array of included accessories.

BPA and Latex Free
Sometimes the products we buy contain harmful chemicals or irritants. For people with allergies, these are especially important items of consideration when purchasing products. The Live Infinitely Exercise ball is designed to mitigate this potential problem by being BPA-free and containing no toxic chemicals. It also is latex free, a boon for those among us with latex allergies.

One Year Warranty
Sometimes life happens. Accidents occur, and the only one at fault is circumstance. When times such as these occur, it is often frustrating and tiring. Live Infinitely has included a one year warranty on their product in order to alleviate this particular headache. If something goes wrong with this product, the warranty will make it easy to get the situation rectified and get you back on your fitness regimen.

Cost and Value
When considering only the largest size option available, this is the second-least-expensive item on this list. Coming in with six colors to choose from, being allergen-free, having an anti-burst design, and considering all the included accessories, this product has a lot going for it. It has all of the standard features other similar items possess while maintaining an extremely reasonable price point.

Cons:

Dynapro is a company that specializes in exercise equipment. Their product line features a variety of items, such as resistance, bands, exercise balls, and jump ropes. However, they also sell nutritional products, such as blenders. Overall, this is a one-stop shop for your fitness and nutrition needs. The Dynapro exercise ball has a ribbed body for grip, can handle up to 2000lbs of pressure, and comes with a handy pump included.

Inflates Quickly
If you want to take your ball with you, say to the office as a chair, or to the gym for a workout, inflating it is the most annoying and time-consuming part. However, the Dynapro inflates quickly when compared to other balls on the market. It can be inflated to full size in just a few minutes so that you can get on with your workout.

Puncture Resistant
The Dynapro has two special features in its coating. The first is that it is puncture resistant, with a special PVC coating. The other is a safety feature built into the design. If the ball suffers a puncture, it will leak air slowly. This will not only allow you to finish your workout but prevents the dangerous explosions that can occur with some other similar products when they are damaged.

Cost and Value
There is a price range on these items, depending on which size you decide to purchase. When only taking into consideration the largest size, this item is one of the least expensive on the list. Despite its low price, its built-in safety features and included accessories (such as the included hand-pump) make it a winner when it comes to value.

Criteria Used for Evaluation

Size

The sizing on exercise balls generally ranges from 55 centimeters to 95 centimeters, in increments of 10 centimeters. Depending on your weight and height, the size you choose will vary greatly. If you’re only five feet tall, getting a 95cm option is probably not the best idea. However, the recommended size will also vary greatly with your intended use.

Materials

Pounds of Pressure: When investigating these products, you’ll see the term “pounds of pressure” thrown around. Simply put, this term means the amount of weight that it can handle before it will burst. The number usually ranges between 2000 and 2200 pounds of pressure.
PVC: PVC is extremely common in fitness equipment and accessories across the industries. You can also commonly find it in yoga mats. It is a synthetic material that is extremely durable and hardy, which is a trait that is desirable for equipment that is designed to take a beating (sometimes quite literally).
Phthalate-free: Phthalates are a kind of chemical that is used to increase elasticity in products. This group of chemicals, however, has been shown to demonstrate significant health risks, especially to children. You’ll want to be sure to double-check that any product you purchase is labeled as phthalate-free.
Rubber: While PVC is by far the most common material used, sometimes a company will opt for the all-natural route instead. Aside from not only be better for the Earth, but rubber is also just as hardy as its synthetic counterparts. However, products made from this all-natural material do tend to cost a bit more.

Accessories

Resistance Bands: To get your arms, and sometimes even legs, toned up, occasionally you’ll find a product that has included resistance bands. Though not every product comes with resistance bands, the higher-priced ones usually do, especially if they already include a stability ring.
Exercise Guides: Though we order products, sometimes we aren’t 100% sure how to use them. To remedy this problem, a good amount of companies will include a guide with your purchase. This guide will at the very least be in the form of an information pamphlet. However, digital guides in the form of a DVD are becoming more pervasive.
Extra Plugs: It’s simply human nature to misplace things. Some companies will take this into account and include extra plugs. This tiny piece of plastic is incredibly important to the integrity of your exercise ball – but it’s also tiny and extremely easy to lose.

Stability

Some products will come with an included stability ring. This is essentially a ring that sits around the base of the ball, preventing it from rolling every which way. This ring is useful if you are using your exercise ball as an office chair, and don’t want to risk falling off as your mind is on other tasks. It is also useful during high-intensity workouts that involve a lot of movement

How often will I have to re-inflate it?

Usually, you should check the ball every two weeks and top it off as needed. However, some products are more airtight than others, and only need to be refilled every month or so.

What is phthalate?

Phthalates are esters of phthalic acid. These chemicals are generally added to plastics (especially PVC) to improve their flexibility, transparency, durability, and longevity. However, these chemicals have been shown to be toxic to humans, especially small children, and have been linked with several health concerns.

Other Factors to Consider

Portability

You can incorporate it into your yoga routine. You can do aerobics with it, incorporating its bouncy, elastic nature. You can strengthen your core while simultaneously lifting weights from a seated position. You can even take it with you to the office as a healthy replacement for your uncomfortable desk chair, with the added perk that it will improve your posture. The uses are seemingly endless. Yet despite being so simple in its design, there is still a huge rainbow of features to sort through.

Are the ribs for support more important than a non-stick finish? Do you just want a simple, basic model, or do you want something that comes loaded with accessories? Once the product has arrived, what are different ways you can use it? Also, what’s the deal with the stability ring? We’ve assembled answers to these and other questions below to ease your journey into the world of exercise balls.

Frequently Asked Questions

q: Can I use this on a wood floor?

a:

Most exercise balls are designed to be used on any flat surface, such as carpet or wood. The only place it is recommended against using items such as these is outside. You don’t know where sharp items or piece of glass are lurking that could puncture it.

q: Does this double as an office chair?

a:

For sure, you can swap out your office chair for something that’ll give you a chance to work out your core and improve your balance. The only consideration would be both your height and the height of the desk. You want one that lets you plant your feet firmly on the floor, but isn’t so short that you are unable to reach your desk.

q: Can I use this if I’m heavy?

a:

Definitely! Most products are built to handle 2000 or more pounds of pressure or weight.

q: What size should I get?

a:

This depends on you! If you’re shorter, you should get a smaller size. If you plan on using it as a chair or to do seated workouts, you’ll want your feet to be planted firmly on the floor for stability.

q: What are the pounds of pressure rating?

a:

This refers to how much weight, or pressure, the product can handle before bursting. Considering that no one using it is going to approach anywhere near 2000 pounds, you’re safe.

q: Will it explode?

a:

It shouldn’t! Only in very rare cases will defective units burst. However, if you drastically over-inflate your ball, you may risk it exploding. Pay very careful attention to how much air you’ve put into it.
