After letting the mattress sit for about 36 hours, we tried it out for one night. I have terrible back pain from my work but this mattress was like sleeping on clouds. Very comfortable

Excellent!! Soft, perfect when you add a 3 inch egg crate topper, and a bamboo topper! (Bad back). The bed I ordered will tell the tale when it gets here Monday. Otherwise, this mattress alone is well worth the price just by itself. I definitely would buy again, and may do just exactly that. Excellence!!
