Cooling Blanket is a sleep saver for me!
This is the second product I have used from bedsmile and as with the other one, this is a great product! It truly is a cooling blanket. I am a very hot sleeper and live in a hot, humid climate, so this has been a sleep saver for me! One side is silky smooth and feels so good on your skin. The other side has a texture to it which is great if you want to use it as your only bedding, which I do. It covers well and hangs over the edges as it should. I ordered the white one and it is bright and unblemished. The silky side magically feels much cooler than typical bedding and keeps me cooler during the night. It is lightweight but heavy enough to make you feel that you are "under the covers". In my opinion, putting additional covers over it would defeat the purpose but if you live in a cooler climate, it would still be beneficial to use this blanket as the silky coolness would help get a good night's sleep anywhere. Another great benefit of this product is that it does not have any strange odors when unpacking. I did wash it before using, but honestly, I am not sure it was necessary.

Incredible Value - Soft, Stays in Place, and Military Son Approved!
Size: California King, Size: California King
I purchased this mattress topper for under $27 and I'm so impressed that I'm planning to buy another one!
Easy Installation & Perfect Fit:
This topper was incredibly easy to put on, and it fits my California King mattress perfectly. The 18-inch deep pockets ensure it stays in place - I can move around on the bed and it doesn't shift at all.
Comfort:
The topper is wonderfully soft and has made a noticeable difference in our sleep quality. My husband absolutely loves it, and we both wake up feeling more rested.
The Ultimate Test:
My son recently came home after being deployed for a year. He slept on our bed for hours and immediately commented on how soft and comfortable it was. That's saying something for someone who's been sleeping on military accommodations! He was so impressed that he's planning to buy one for his ship.
Bottom Line:
For the price, comfort, and quality, I recommend this 100%. It's hypoallergenic, stays in place, and has exceeded all our expectations. You can't go wrong with this purchase!
