I love this cushion. I work at my desk pretty much seven days a week and the pain in my back and legs are gone.
I wish I had ordered this cushion when I first started working from home because the difference in booty-happiness is incredible. Seriously your tail bone will thank you, I'm not stressing this enough....YOUR BUTT BONE WILL BE SO F$%^ING HAPPY!!!
This cushion has made a huge difference in the past week since I got it, and really reduced my back pain. I use it on my office chair and for yoga/mediation. I'm going order another one for husband as a gift.
This thing saved my back when I worked a desk job. I would get pain from sitting so long no matter how "supportive" the chair. I used this for over a year without it breaking down or losing support. The cover is machine washable. Love it!
