Great mattress! Purchased two for daybed with trundle. Guests always compliment on the comfort of the mattress.  They always seem to mention loving the fact that they barely turn over throughout the night which allows for a good night's sleep. Mattresses do arrive compressed so I allowed them to air out for a couple of days before putting on sheets. They had a slight odor but went away in a few days. Will be purchasing one for my father since he slept extremely well when visiting for a week. That says a lot since he's diabetic and tends to get cramps during the night. He didn't get any cramps on his legs or hands when visiting.  I've had the mattresses for 4 months, hope they last for a while.
