Gaiam Balance Disc Wobble Cushion Stability Core Trainer for Home or Office Desk Chair & Kids Alternative Classroom Sensory Wiggle Seat

Didn't really work for me. Did not like that I have to inflate it but not sure what gadget to use to inflate it, so currently works as a leg rest for me as was not comfortable on my chair.

not comfortable for sitting

Me ha gustado mucho para trabajar (especialmente al usarlo en el piso y de pie), mi espalda termina mucho menos cansada al acabar la jornada, haciendo balanceos y cambiando la posición de las piernas siento que también las ejercito y me ayuda a concentrarme.El material se ve resistente, llega parcialmente inflado pero realmente no necesita más aire. También me ha funcionado como soporte lumbar al sentarme en sillón.Durante varios días tiene un olor muy fuerte a plástico, pero se va reduciendo.Me gustó mucho

I bought this for my office chair as I spend far too much time sitting most days. I love it, and so do my colleagues, I often return to my desk to find someone has ‘borrowed ‘ it. One of them ordered their own after using mine while I was on leave for a couple of days. It came inflated so was ready to use and is a great colour (I got wasabi). I don’t have any back problems but used to find my lower back was stiff at the end of the day but not anymore.

It’s big enough to sit comfortably and there’s no need to set up :)

This has been great to take the pressure off my lower back
