It’s a thin 10” mattress but the feel is remarkable. I like a mattress that is just a little medium firmness, but it conforms to you body. It releases back to normal form within minutes.

Be prepared to open the box and let it open for 2 days. After the first day I stood it on end so it would open all areas rather than just leaving it flat. There was no odor at all in the mattress.

Have been sleeping now for a week and have been having the best sleep in a long time.
I did not need a box springs. I had purchased a wrought iron bed headboard and frame on Wayfair which had 12 steel slats and cross bars
