I was going to get a memory foam topper for the 10 year old queen bed in our spare bedroom. It was pricey. After shopping around Great Offer Stock I found this mattress had good ratings and was only a bit more than the topper. It arrived in a big box. After putting it on the bed, it aired for a couple of days. If you're looking for a fluffy pillow-top mattress this is not for you. I would say it sleeps just like a firm mattress. It has similar qualities to the King *** mattress we purchased 12 years ago. This mattress is more advanced as it has a cooling gel top layer. I recommend it, but expect a firm sleep. It may break in (soften) over the months as we've only had it a few weeks now.
