Lumbar Support Posture Corrector Chair for Men – Large Portable Ergonomic Back Support Chair for Posture Correction and Lower Back Pain Relief

This does help with lumbar support, but I paid more for this particular one vs other cheaper options hoping it would have enough cushioning on the bottom. I feel like it could have more gel support for your butt. I ended up buying a gel mesh pad, as it was a little uncomfortable for extended use without something.

It did help correct my posture, but the hard plastic chair had little padding. Unfortunately, this became extremely uncomfortable.

This product seems to be doing what it should. My husband uses it for his work chair

This unit is a solid plastic mold with gel pads. The universal fit is nice - it should fit most chairs. The trainer does force proper posture in any chair. The down side is this unit still seems possible to slide off of the chairs - it would almost be better to include a strap to secure.

Sitting on this is not exactly enjoyable, but that's ok. I have a bad habit of slouching when at my computer desk. This support chair makes that fairly impossible by continually reminding me to sit up straight like an obedient school student in the olden days. If you slouch at all it will dig uncomfortably in to your back or legs, which quickly reminds you to correct your posture. Unfortunately, even when sitting properly, the bottom is not very comfortable. There is some slight padding but I can feel the hard shell of the seat pressing up under my legs.So all in all, this is uncomfortable no matter how you slice it, but it does a great job of correcting poor sitting posture.
