Review on Tumaz Wobble Cushion: The Ultimate Solution For Improved Posture, Focus, Pain Relief, And Core Strength by Shawn Martin

This has been a really great product. I've been setting up a work-from-home office and suffer back pain after an injury that sitting for long periods can make flare-up.I was about to buy a new, ergonomic office chair to help my back pain, but hesitated and decided to try this instead as an intermediate measure. I don't regret it and haven't been shopping for chairs since. I've had a really sturdy but otherwise not ideal old retro steel-and-vinyl kitchen chair with a wide seat at my desk at home for years, and I almost always worked outside of the house before the pandemic so it was fine for the few hours a week I spent working at home. The pain isn't a joke lately, though, and I'm really glad I got this. The chair's seat is large enough that the cushion doesn't take up the whole thing, so I can shift around on it without getting anywhere near it sliding off (it also isn't slippery, but it's nice to not worry about).The texture is nice, I love the color options (the aqua blue looks as pictured), and I don't really notice that I'm sitting on it most of the time. I read some reviews of other products where people noticed a big impact in their core muscles, and I'm not sure if it just doesn't hit me that way or if the build of the other cushions works differently, but this has totally relieved my pain from sitting. I bought a previously-returned item in 'like new' condition, gave it a clean, and pumped it up a tiny bit. It's held up ever since, maybe deflated a bit but nothing needing refilling after a couple of months. I'm not even sure I know where the pump is since I used it on the first day (oops). I sit on this thing for six hours a day at 150ish lbs and a tendency to fidget, reposition, and rock back and forth often. I haven't tried it as a workout item yet but it seems sturdy enough.If you're having back pain and dreading the chair shopping, definitely consider it!
