Excellent purchase. Delivery was right on time. The mattress is very good quality. I have slept very well. It's firm, but soft on top. I have problems with my rottary cuff and cannot normally lie on my side. This mattress seemed soft enough feeling, that I thought i'd try to. However it's softer top layer is just for comfort, and it is in the end more of a firm mattress, but very comfy. I will continue to enjoy lying on my back. Normal folk without an injury will be fine in their side.
