The best ever!
I don't normally write reviews but was so impressed that I had to share it anyone who wants to read.  I got this seat along with 2 twin xl mattress.  I'll talk about the seat first.... Of course I had to do the egg test and as advertised, i sat not the egg and it didn't crack.  My husband didn't believe me, so he pushed me down and thought for sure that it would break but when we checked, we were both surprised that it was intact. I've had this seat for over a month but decided to give it to my mother in law since she is more sedentary due to her illness and spends more of her hours sitting in the chair.She absolutely loves it. no skin breakdown and is very comfortable in her chair now because of the seat cushion.<br />For my mattress, I love it!!! i have a chronic back problem and have had a cervical and lumbar fusion.  I've been miserable for years and have had not a good night's sleep for years.  I've purchased very expensive mattresses including the memory foam with the same result....chronic back pain and restless nights.  After purchasing this, I'm now happy to say that i am getting my recommended 8 hrs of continuous sleep.  I don't wake up with a gnawing back pain.I am so glad i got this.
