Good value memory foam

I purchased this on sale for our guest room and so far everyone finds the bed to be comfortable without feeling hot.. The density is good did not smell when opened.

I may never leave my bed!!!!

Inflated beautifully in 1.5 hours. Is exactly what I was hoping for, added a soft cushiony sleep spot for my old lady bones. I added a 2 inch down alternative topper and it's like sleeping on a cloud.If your looking to soften up your bed, buy this. I'm glad I didn't buy the more expensive brand. This is perfect.

Cooling Memory Foam Mattress Topper

The Cooling Memory Foam Mattress Topper comes vacuum sealed. You cut the packaging and lay it out and over a few hours the Memory Foam Topper will pull air back into the and will grow thicker eventually reaching the three inch thickness. I really like the blue color, since it is a cooling mattress topper the color blue is absolutely perfect for it. I am really big on blue as a cooling color, it is my favorite color! It adds a nice softness to the bed and adds a layer of comfort which is very nice. I got this mattress topper for my sister to make her bed more comfortable. What better gift can you give those you love than a better nights sleep?! The Serta Cooling Memory Foam Mattress Topper would make a great gift for any occasion and is one that will last a very long time!
