The Plush Gel Memory Foam Mattress arrived just in time for our grandchildren they were excited to hear about our new mattress because they had to sleep on a brand new sofa bed before but complained about the spring filled mattress.  We were worried about the smell from reading the other reviews but we left the sofa open for a day and there really wasn't any but the Plush Gel Memory Foam Mattress had time to expand to it fullness.  We tried it that same night before the grandchildren and found it to be so much nicer.  Thank you
