  • Cold, cold topper, but works as a bottomer.
Size: Twin (38x75x3 inches)
It is a cold, cold topper and I do not like being cold. I unzipped the cover and washed it. I walked on the uncovered topper in my thin socks and my feet got cold. I had a pillow with blue colored pieces of foam and it was too cold. Fortunately, I had extra foam pieces and was able to salvage that pillow. There are six rows of blue foam stars at each end with 5 rows of white foam stars in between. These rows of foam stars are sandwiched in between two flat sheets of foam. The top sheet is softer than the bottom studier sheet of foam. I'll use this with a sleep number mattress that I already have and will put it UNDER the inflated mattress. There's room for it because I got rid of the rigid border and substituted foam from another complete foam mattress that I tried. I initially carved out room in the foam mattress to put in the sleep number inflated mattress. Then I removed all of the inner foam and just left a foam ring around the sleep number mattress. I got one of those Tempur-Pedic mattresses that comes in a bag. It is too soft for me. I had a lumbar laminectomy in September of 1990 due to a herniated disc. I was putting the sleep number mattress on top of the Tempur-Pedic mattress when I ordered this topper. But I got the bright idea of removing the sleep number mattress and flipping the Tempur-Pedic mattress over with the much firmer side up and that was working for me (see below). The sleep number mattress was causing a pressure point discomfort at my hip joint. I am a side sleeper and switch sides during the night. I also need to sleep with a pillow between my legs. I only got up once last night vs 2 or 3 or 4 times with the sleep number mattress, depending on the temperature and hip pressure point discomfort. So, it's all good and I'm keeping the topper. I knew I could use it even though I feared that it might be cold. It is COLD folks. Don't let anybody tell you otherwise. I did put the topper on my bed but had to take it off a few hours later. I need to be able to lay flat on my back with the head of the bed elevated a little to watch TV/Netflix. I have a middle back injury that affects my stomach. All of those foam star springs were pressing against my back, and I got a stomachache after a few hours. At least I tried. You never know for sure unless you try. Otherwise, I might've kept it on for the rest of the summer and then removed it when the cold weather hit. (Update 9-1-2023) The Tempur-Pedic mattress started bothering my lower back injury so I got up in the middle of the night and put the sleep number mattress back on top of the Tempur-Pedic mattress. In the last photo I show the bottom side of the sleep number mattress after I stuffed the topper on top of it. That is the side that I am sleeping on. So, the topper is on the bottom of the sleep number mattress. The soft foam of the topper is facing down. But that means it is facing up when I sleep on the sleep number mattress. That's because I flipped the topper core before zipping the cover back together. If you didn't do any of that then you can achieve the same effect by making the top of the topper face the bottom of the sleep number mattress. I can lie flat on my back on the sleep number mattress and it doesn't bother my middle back injury. I can side sleep on the sleep number mattress and the pressure points at my shoulder and hip are much better with the topper acting as a bottomer. So, I upped my score from a 2 to a 4 and am happy with my purchase. ... show more

  • Dormeo Relieving Octaspring Technology Mattress Topper
Size: Queen (60x80x3 inches)
The main reason this topper was purchased was for its cooling affect. But it does not cool as advertised. It is a very comfortable topper to sleep on until it starts warming up with your body heat. The manufacturer should have left the cooling capability off its ad. Too much money for a not-as-advertised product. ... show more

  • It doesn't last!
Size: King (76x80x3 inches)
I bought this one year ago to cover a little too hard Saatva all spring mattress. At first, it was fantastic just as most other reviewers have said. Here we are one year later and it is worn out. Yes, I spun it every three months to keep it from getting body impressions, but there they are. It has become almost solid in the shoulder areas. There is no warranty when purchased from Amazon. The link above says to contact Dormeo where they say they only warranty the product when purchased directly from them. I bought from Amazon for the fast free shipping. Would I buy another Dormeo? Maybe. First, I'm going to cut the top off of this and see if I can rearrange these Octasprings and try to get another year out of it. This thing was $500 with sales tax. This should last longer than one year. One more thing: it would be great if this came with a zip off top so we could rearrange the Octasprings when they start collapsing. ... show more

  • No complaints
Size: Queen (60x80x3 inches)
I think the mattress pad is a good product. I sleep good on it, but I really didn't have any sleep issues. But I can say the pad didn't cause any issues for me, I still sleep good. But I also think I might not be as stiff when I roll out of bed in the morning. I really bought the mattress pad for my wife. The main thing she has always complained about when she sleeps is getting too warm. She still gets warm, but she thinks not as much as before. She has always been warmer than me. When she sits on a chair and gets up then I sit on it the chair feels like it has a heating pad on it. It's something else. ... show more

  • Worth every penny and then some
Size: Queen (60x80x3 inches)
I saw a paid advertisement for this at 5 in the morning one night and figured I'd give it a shot. This has honestly changed my life, I haven't had a good night's sleep in years and years, after a week of sleeping on this topper, I am out like a light, my back pain has minimized and I feel rested when I wake up. This may be a bit more pricey but it is 100% worth every cent I paid for it. ... show more

  • As advertised
Size: Twin (38x75x3 inches)
This Topper exceeded my expectations. After airing it out for two days there was no noticeable odor. The comfort of this Topper was noticeable after the first night. I now wake up with out the numerous aches and pains I've had . And for the first time in years I have no lower back pain from sleeping on my back! At first I was hesitant of this purchase because of the price. Am sooo glad I went ahead with it. It is unreal that after years I can get up without feeling as if I was in a train wreck every night. ... show more
