I have been a strong skeptical of this new technology of getting a mattress delivered to my home in a box! My first thought has always been how comfortable can that be?  It must be a super thin mattress! I have to tell you I stand 100% corrected! This is a such a comfortable mattress you will not need to count “sheep” to fall asleep! It has a support core memory foam, not coils, that helps to keep the mattress and your body supported. Antimicrobial and also has a great warranty! Would definitely recommend!
