Trideer Yoga Ball for Exercise, Pregnancy, Active Sitting, 55/65/75cm

First, love the purple color. It’s like a muted grape hue. Packaging was good. Comes with pump, instructions, 3 plugs, plug remover, measuring tape (see photos). The deflated ball looks really small when you first take it out of the packaging. Don’t worry, it’ll inflate to size. A lot of people’s reviews says the ball doesn’t get to size. When I first started pumping up the ball, I got it to inflate to the lower end of the size range (55 inches) pretty easily. Took about 10 min of constant pumping with the included pump. I waited a few minutes and then added about 20 more pumps of air, waited a few minutes again, added more air. Eventually, it got to the high end of the size range (65 inches) without too much extra effort. The whole set up took maybe 20 minutes. The instructions say to wait a day after you initially inflate the ball if it’s not getting to size, then add more air to allow the PVC material to stretch, but I didn’t have this issue. The only thing slightly negative I’ll say is that if you are looking for a specific sized ball and want it to be on the softer side (more give when you sit on it), size up. I inflated my ball to 65 inches (max for the L size) and it’s pretty hard, not a lot of give when I sit on it (then again, I’m on the smaller size). The overall size of the ball is good and what I expected, but I think I would’ve preferred an XL ball that’s not as inflated. For reference I’m 5’3” and 115lbs and I bought this ball for gentle exercise/stretching and for early labor. The current height of the ball fully inflated would also make it perfect as a desk chair as well and the firmness would be ideal for sitting for longer periods. My feet touch the ground fine and it’s easy to balance on it. If it were any squishier, I don’t think it would be an ideal desk chair as I’d sink into it too much. Overall, it’s a quality ball, just make sure you’re ordering the right size. I’d recommend getting the size where your expected size falls in the lower-middle inflated size range.

I purchased this exercise yoga ball with the intention of using it for stretching after recently having surgery, since I’m unable to go back to the gym or do rigorous workouts. After a month off, I found myself feeling really weak, and this seemed like the perfect way to gently stretch and start building strength again. The ball is very durable and well-made, and it was incredibly easy to assemble/blow up. I’ve only been using it for two days, but I can already feel the soreness in the mornings, which tells me it’s helping! So far, it’s exactly what I needed for low-impact exercise and recovery. Absolutely love the color as well! Highly recommend for anyone looking to regain strength safely at home or use for at-home yoga. Although I am 5’9, I did purchase the ball in size Large.

Used during pregnancy. Worked great. Good quality, easy to use and fill up. Will fill to complete fullness over multiple days and it was perfect. Comes with pump and "key" to get the plug out easily. Great value.

I’m wfh and my office chair was giving me bad back aches. I bought this to replace it and love it!! This is for sure too low for an office chair however I enjoy stretching, working out, and especially not having back pain anymore since using it! Plus love the color

This Trideer ball really said “physical therapy AND toddler entertainment center.” As an exercise ball, it’s solid, sturdy, and great for stretching, balance work, or core training — very “I’m improving my life” energy. But the real plot twist? Your toddler will absolutely claim it as their personal bounce orb. Dual‑use king. One minute you’re doing stability exercises, the next minute it’s a tiny human launching themselves into orbit. It holds air well, feels durable, and doesn’t get weirdly squishy over time. Not perfect, but definitely a reliable addition to both your workout routine and your kid’s chaos routine. Rating: 4/5 — great stability ball, elite toddler trampoline.

Sturdy and I liked it

Took forever to fill with the pump and is bigger than I thought I’d be but it gets the job done. I’m pleased.

Great quality. Thick and durable - overall a great product for the price.
