Cool and soft.
Color: Gray Size: Queen
Seems to keep sleeping temps down. Adds extra layer of softness to mattress top.

Fits perfectly, very soft and thick cushioning
Color: White Size: Queen
I put a heated mattress pad on the mattress, and bought a different mattress topper pad to cover it so you wouldn't feel the wires. It turned out to be a fairly thin mattress topper pad, and the wires were still somewhat noticeable, so I bought this mattress pad to put over the other one (and use them both.) This one is thick enough that it may have covered the wires well enough by itself, but I went ahead and used both since I had them. This one is very plush feeling and soft & thick, the sides don't seem all that deep but it did cover my mattress easily, but if you have an extra thick mattress, it may just cover it. It goes just a bit down over the edges all the way around, so you won't feel the edge of the pad when sleeping. It is a very nice mattress pad & I am really happy with it! ... show more

Yes a bit cooler, nice price for what you get
Color: White Size: Twin
I got this mattress topper because I was often too hot on my foam mattress. I would wake up sweating and found it hard to get back to sleep. The first night I tried this Sleep Zone Cooling mattress topper, I did feel cooler and did sleep better. However on the 3rd night I still woke up sweating (but not as bad as before with the old mattress cover). This Sleep Zone Cooling mattress topper seems to be well made. It has a nicely cushioned and quilted top with a generous all-around pocket which should fit just about any thickness of mattress. It delivers a lot of value for the price. Just don't expect miracles. ... show more

Made an institutional foam mattress comfortable
Color: White Size: Twin XL
My son and I just got back from the CMP National Match at Camp Perry. This year we stayed in base housing and had been warned that the foam mattresses left a lot to be desired. I got a couple of these mattress pads and we were both glad we had them. The very firm foam mattresses were still very firm but this mattress pad put a soft layer between me and the vinyl-clad military mattress. I slept very well. The sheets stayed put. My son was so impressed that he's taking his back to college this fall. This easily fit on the "Twin XL" mattresses provided. They do arrive rolled and compressed. Once they decompress, they take on the quilted appearance. I washed them before and after the trip and they've held up well. If anything, the first trip through the washer and dryer helped puff it up even more. This is NOT memory foam and it will not add anything appreciable to mattress thickness. This just adds a pillowy layer between your bottom sheet and the top of the mattress. If you've ever slept on an institutional vinyl-clad foam mattress, you'll appreciate why that's important. I can't recommend it enough. ... show more

Super comfy, not very cooling
Color: White Size: King
I was really hoping that this mattress pad would be cooling, but it wasn't. It's very plush and comfy though.

Helps with night sweats
Color: White Size: Full
I got this because we life in good old florida and anyone that lives in the southern part of the us can tell you that summer feels like you are stuck between the devil's buttcheeks. The humidity makes you feel like you just stepped into the sauna and the sun feels like you just took a trip to Mordor. So I got these to help us at least stay a little cooler at night and not wake up feeling like we just took a dip into a hot spring. It has stopped the night sweats and being paired with cooling sheets it has helped our bed feel more comfortable and has made sleeping a way more pleasant experience. It has a decent amount of padding and it fits the bed perfectly. I didn't notice any outward bad smells when unpacking it but like with anything new fabric wise we did run it through a gentle cycle. ... show more

Thick and comfy, a bit too warm but good price
Color: Gray Size: Twin XL
I bought this hoping it would soften my new split adjustable bed. My husband loves the bed, but it’s way too firm for me. While this doesn’t cool as I would like, I tend to be super hot so it’s probably fine for most people. The price is good, the quality nicer than expected, and it fits perfectly. It does add about an extra almost inch compared to my husband’s side, and I can tell it’s softer than without anything. Stays in place well. I’ll still probably buy a topper to make my side extra soft, but will keep this as well. It doesn’t move around and sheets fit better with it in place. ... show more
