    • So comfortable!
I recently got the Sleep Innovations Cooling Comfort Gel Memory Foam Dual Layer Mattress Topper, and it has totally changed how I sleep. The mix of gel memory foam and the pillow top cover is super comfy and supportive. The cooling feature keeps me at the perfect temperature all night, so no more overheating. Since I put this topper on my California King bed, I’ve been sleeping so much better. The only downside? It’s so comfy, I never want to get out of bed in the morning! Highly recommend this mattress topper if you want to up your sleep game. ... show more

    • Very comfortable
Great mattress topper for the price! I purchased this topper along with the 14in Shiloh mattress from this company and I am very pleased! So comfortable and supportive. I’m finally getting good sleep without any pain. It’s a medium feel but still soft. Very happy with this topper!

    • Terrible
We were so excited for this, but we didn’t even get to use it once. Before we ever put it on our bed we washed and dried the cover as directed (including using dryer balls as specified). We took it out to find the cover had rough, crusty spots all over it. I’m so sad. I was so looking forward to this - it seems so nice, but it just didn’t hold up to even one washing. I’m so disappointed. ... show more

    • Well Made, Comfortable but cooling feature doesn't seem to work
Works very well and gives support while being softer than our mattress. That part is really nice because I hate sleeping on a hard mattress. It appears to be well made. The Gel Memory Foam does have some odor, but it was not overwhelming and goes away as time passes. We have been sleeping on it for several weeks. It seems cool enough when we first go to bed, but several nights I frequently wake up sweating. Since that didn't happen before we started using this topper it seems their cooling feature doesn't work well. ... show more

    • Not four inches....
The foam pad is great and definitely makes my old mattress more comfortable, but the mattress cover I received is DEFINITELY not two inches.....

    • Exactly what I was looking for
Love this At first I didn’t think it was going to fit my California king. It takes a while to puff out. It’s very comfortable and cooling. I highly recommend.

    • Buy the Serta instead for the same price!
Doesn’t compare to the name brand for the same price! I have a Serta mattress topper from Kohls in my spare room. When my mattress started feeling a little firm I decided to try this because it looked very similar, big mistake! Sleeping on top of this felt like being on top of jello, still resulting in waking up 3-4 times a night in discomfort. I bought another Serta one from Kohls and was just as impressed. Just good luck fitting this thing back in the box for a return! Side note, in the week we tried this, the cover was already starting to pill all over. ... show more

    • It's About Damn Time!!!! YES
Where have you been all my life? My topper came today, Yay. I we put it on the bed and.... I almost cried!! I am 5'11 and had back surgery in 2013 and total knee replacements in 2017, with resent shoulder pain. I truly need all the support my body can get. When I say, Comfort, I mean Outstanding! Mind you, it was delivered 6hrs ago. This 4' dual topper is worth every penny! Surprisingly pleased after being disappointed by other toppers. I ordered one for my son's firm bed and added the memory foam pillows! I am sure he will love it too. P.S. My son loves his topper!! ... show more
