Needed a mattress as a supplement for an existing mattress that was basically worn out, yet wanted something more versatile and transportable as a futon mattress would be. I searched for weeks knowing that any mattress purchase would be a risky venture. I decided to take a chance on a Serta based upon the descriptors on this site. After a month, I am enjoying great sleep without any aches and pains that the mattress underneath caused. The color is beautiful, there are no lingering odors and so far, it is retaining shape and the plush/support combination is perfect for me.
