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.

This memory foam mattress topper is heavenly soft

The Serta Cooling Memory Foam Queen Mattress Topper has a 2" layer of blue, breathable ThermaGel foam that keeps you sleeping comfortably. The dimensions are 2" thick by 59" wide and 79" long. The package comes super compressed and rolled up in a little zip carrier (weighs about 15 lb total). It took less than an hour to fully expand and it does have a weird chemical smell at first (but it goes away within a few days). This is common with many mattresses that are shipped and rolled up in boxes. I have slept on this a couple of times and I'm not overheating like I normally do! Currently, it is topping a 12-year-old spring mattress and it is amazing at relieving pressure in my achy back. This is definitely an affordable way to upgrade any old mattresses - especially the ones in guest rooms. I highly recommend this product!

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!
