Review on Standing Sitting Perching Ergonomic Computer Building Supplies by Terence Dardant

So uncomfortable! I am a healthy fit woman who purchased this to use on my 36" drafting table. My old chair gave me back pain and I thought it would be a great alternative. While I like the idea of it, the swing part is cool and the thing is well built. The seat is TERRIBLE! It's shaped like a domed mushroom tip, and the foam is so round and dense that it hurts after sitting for a while. like the top in the photo. It really looks like a round top. Now, while my back feels better, my tailbone hurts so much it feels like it will. I'm sending it back. Sorry I didn't believe the other reviewer who said it was like sitting on a rock. Look out! A. And while it's easy to assemble, it's impossible to take apart, so I have to buy another big box to send it back. Sadness.
