HYLEORY Full XL Cooling Mattress Pad - Quilted Fitted Mattress Protector with Breathable Fluffy Pillow Top, Soft Mattress Topper for 8-21" Deep Pocket Beds | Perfect for Hot Sleepers & Guest Room Comfort

I bought this to add on top of our foam mattress topper I added to our new motor home to help soften the factory bed. the foam was making my hubby run hot and he didn't like the feeling of the contours it had either. So added this in hopes to help cool things off and get rid of the feeling of the foam contours. Ran it through the dryer on our "sanitize" setting to fluff it up which worked great.It did help keep the bed a tad cooler. As many mention it doesn't have a "cooling" effect, not sure why they market it that way. Its not cold when you touch it and will heat up with your body heat like any other bedding. There is no miracle fabric that will stay cold after you lay on it...maybe someday. The point is to allow for more air circulation, which it did seem to provide. He said he still got hot but it was much better. He just sleeps hot no matter what.The extra padding did get rid of the foam contour feeling, so that was nice I must admit. Although it didn't bother me I do prefer the smoother soft top. It added a nice softness and cozy feeling.Also we have a "king" bed in the motor home but its not a full king but also bigger than a queen...sigh...I swear they do this just to mess with you! I got the queen size topper and its a couple inches short of the edge but considering you don't generally sleep on the very outer edge didn't think it would be an issue, and its not. I was worried the king was going to be too big and hang over the edge, our mattress is really tight to the side tables so I didn't want to add more bulk to the width. The queen fit nice and snug over it just fine and the couple missing inches didn't bother either one of us at all. Just FYI if you are looking at this for a weird size RV mattress., a size smaller is fine - it has deep pockets that were plenty big enough to fit around and hold it on tightly.All in all, it seems like a good product, provided nice padding and air circulation to help make the cheap factory RV mattress something we can use for hopefully quite some time. Too many other expenses right now to worry about replacing the mattress, so a couple inexpensive toppers make it quite cozy.
