Review on 🛏️ CALM NITE Mattress Pad Protector - Waterproof Cover, Vinyl Free Topper - Machine Washable - Twin 39 x 75 | Buy Now for a Peaceful Sleep! by Carmen Martinez

This mattress cover captures all of your body heat and keeps it there until the bed gets unbearably hot. It's not a bad thing when you go to bed, but my husband and I wake up hot and sweaty every night since we put it on the bed. We sleep with a sheet and a light blanket and keep the room temperature around 70 degrees and we sleep with a fan. If we throw off the blanket, we freeze on top and our backs still burn. This mattress pad needs to be removed from our bed. We were unhappy. I haven't slept all night since he arrived. This is my most disliked thing I've ever spent money on. However, it appears to be well made and arrived as expected. If you are always cold at night and need something to increase the temperature of your bed significantly, this would be a good option for you.
