Trideer Exercise Yoga Ball Chair with Base for Home Office Desk, Stability & Fitness Ball Seat to Relieve Back Pain, Home Gym Workout for Abs, Pregnancy Ball with Pump

Great customer service! We thought the stabilizer was missing when we received the package so I emailed and they emailed right back saying they would ship me a new stabilizer immediately with no need for any further action on my part. It turned out of course that one of my kids had thrown it out with a different box so we found it and I emailed them back and all was good. The ball is excellent quality. We are very happy with our purchase.

Great product for the Money! Very pleased using it for extra extension sit ups.

Estoy muy contento con la Trideer Silla de Pelota de Yoga. Cumple con lo que promete y ha sido una excelente adición a mi espacio de trabajo en casa. Inflarla fue muy fácil, lo cual fue un gran plus.He notado una fuerte diferencia de color entre el soporte y la pelota, pero no afecta su funcionalidad. Lo más importante es que es muy cómoda para la espalda, lo que me permite trabajar largas horas sin sentirme incómodo.En resumen, es una excelente opción para quienes buscan mejorar su postura y añadir un toque divertido a su oficina. ¡Definitivamente la recomendaría!

I didn’t use the bottom ring because it’s a bit too restrictive for me. I like to roll around. I used to use the ball for work, but have changed jobs so I use it at home all the time.

At first, I thought I should have bought the extra large, but I pumped it up more and it’s perfect. So far I really like it and I hand pumped it also , quite the little arm workout, but so far it works great.I bought the large. It’s like having the hippity-hop I was never allowed to have when I was little.😂

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.

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 ⭐️⭐️⭐️⭐️⭐️.
