Trideer Yoga Ball Chair with Base - Stability & Fitness Ball Seat for Home Office, Pregnancy & Workout

Good value, easy to use, I would make sure no pets get ahold of it. No smell. I didn't use the foot pump nor my battery operated pump I use for other inflatable air beds or toys. I used an air compressor with a needle sprayer attachment. I found it alittle difficult to inflate to a good maximum with the foot pump.It suggests pumping up 80% then 1 day later pumping to the rest of the volume. It was hard to get the plug out after I did that because the plug is a tapered plastic pin, not a flip top. I would suggest pumping up to the full height volume so you don't go through this. Since a week ago ot has help up fine. I weigh 280 at the moment, so this ball holds me fine as I lose weight.

Good item

Should you buy this? If you need a stable all yes.For the price you can’t beat it. Quality is good, love the color, perfect size, soft and thick. The donut it comes with is really nice. Stays in place. Only negative is the pin to keep the air in won’t go all the way in. May create leakage other than that it’s been great.

I pulled it out of the box and gave the included little hand pump a try. Holy cow. That was a workout! Both arms were tired and if you stop, the air back- flows. No thanks. I'll save that for inflating balloons.I broke out an air compressor and filled the ball until it looked taught, but not over-filled. I let it sit overnight. The next day I gave it a sit and felt entirely too low to the ground. I put a little more air in it, but was worried about how much air it could take. I have it another sit and it felt much better... so I worked a full day on it. I had to keep reminding myself to straighten up my back. It takes some getting used to. You certainly can't whirl around to see behind you, like you would in a typical office chair... so when I heard my dog outside the door, I had to twist and crane my neck. LOL. After a day on it I decided it still felt a little low for me. I'm 5'6" tall, with a 28.5" desk, so I got the Large 65cm ball as suggested. I broke down and grabbed the instructions, to make sure I didn't over-inflate it. I measured from the floor, up the wall 65cm, made a pencil mark, then took a straight edge and held it out... I definitely had more room to go to inflate it... and I did! It's at about 63cm now, because I don't like to press my luck. I'm up at a good height now, comfortably resting my forearms on the desk, the keyboard is comfortable and I can still put both feet firmly on the floor. I put the ring under the bottom because I don't want to accidentally bust my ashtabula on this thing. It's comfortable. I can work a very full 12 hr day on it. I push it up so 40% of it is under the desk, and I approach it from the side and swing my leg over it like a horse, then plop my arse down. It's sturdy, has a little bouncy bounce to it, but only when you shift your weight or adjust your legs. It retains air well, so far. Another nice thing is that you can grab ahold of the front of your desk, lift your feet up in front of you, and roll forward while arching your back, until your basically laying on your back, over the ball. It gives a great stretch. Overall, I give it ⭐️⭐️⭐️⭐️⭐️.

Replaced my desk chair with this and I've been using every day since October. Earlier this month it seemed to be losing air pressure, so I bought some of that green tire stuff, which seemed to help for about 3 weeks. I think it's no longer liquid and it probably has another small hole somewhere.Durability wise it's not very good imo. I'm 90% sure the hole was caused by my cat, which I never assumed would be a problem.EDIT:**Support reached out and offered to replace this ball under warranty. It was very nice of them to do this, but I declined, here's why:I did not pay attention to the sizes when ordering, I need the XXL, but this was only L. I did not realize that the inflation instructions were by height, I was just doing it by how it felt to sit on. Likely this was over-inflated and that allowed my kitty to puncture it without much effort. As I stated, it was great until it got pierced.Further, I replaced this flat ball with a correctly-sized XXL ball, inflated to the proper height and it's been wonderful. The support and the warranty really improved my view of Trideer!

It’s a yoga ball, it’s exactly what I expected, so that’s not the issue. I chose this one because it was the right side based on my height and desk height according to the product page. Unfortunately it is far too small to use as a desk seat & that’s why the 3 stars. I’m not returning it because I have another ball that is far too big for me so I can use this for things I was using that ball for. But if I were to order another, I would get 1 size up or one that sits on wheels a few inches off the floor.

The ball and base were super easy to inflate with the included pump. It came with a few extra plugs in case the other ones get lost. The material feels very thick and sturdy, and the aqua color is bright and happy.I have mild scoliosis and a stenosis at L5 which is just above the tail bone. Every now and then it will get inflamed and cause lower back pain. When I tell you the MOMENT I sat on this ball the back pain disappeared, I am not exaggerating. I am going to get another one so I can have them in both my home and work offices.I am just over 5'5" so got the 65 cm ball. It feels ergonomic to sit on, but I am wondering if the taller one would have been slightly better to reach the keyboard on top of the desk. I'll probably wait a few days to inflate it a little more (per the instructions to give it time to stretch) and see how comfortable I am with the height before ordering another one.Edit: It is now fully inflated, and it is the perfect size for my height with a keyboard that sits at 29-30"

Bought this yoga ball while pregnant and used the heck out of it. I enjoyed that it came with a hand pump and extra plugs, as well as a tool to get the plugs out if needed. The base was super nice as well so it didn’t roll all over when stored.
