DUMOS 3 Inch Gel Memory Foam Mattress Topper King - Blue Soft Mattress Topper King Size for Back

I’m absolutely thrilled with this 3-inch king memory foam mattress topper! From the very first night, it transformed my bed into a cloud. The foam is the perfect balance between plush comfort and firm support — soft enough to relieve pressure points, yet dense enough to keep my spine aligned. It also stays nicely in place and doesn’t trap heat the way some other toppers do, so I sleep cool and comfortable all night. The quality feels premium, and after a few weeks of use, it’s holding its shape beautifully with no sagging or flattening. If your mattress feels too firm or just needs a refresh, this topper is an excellent and affordable upgrade. I honestly wake up more rested and ache-free. Highly recommend it! Read more

This mattress topper is ELITE - it comes super compact in a box so it was easy for me to bring inside and unpack myself (vs some of the other bulkier ones I've used in the past). It expands and is the full thickness within a couple of hours so we could use it the same day it was delivered. It definitely feels "cool" to the touch and keeps us comfortable all night long. Totally worth the money! This is the second one of these we've had and it has helped with my hip and back pain significantly since purchasing. Read more

I’ve been sleeping on this “3 inch memory foam topper” for a week now and I just had to REMOVE IT FROM MY BED, it shockingly made all of my PAIN so much worse!!! Its definitely NOT “SOFT LIKE SLEEPING ON A CLOUD” which was what I WAS EXPECTING BASED OFF OF SEVERAL REVIEWS THAT SPECIFICALLY MENTIONED THOSE WORDS and is the very reason why I decided to go with THIS TOPPER instead of all the other ones out there!!! With the price being so CHEAP I had a “feeling” this would be a bad idea but other reviews were saying they were “SHOCKED HOW CHEAP IT WAS FOR THE QUALITY”….. this is NOT GOOD!!! The PAIN it gives me is literally making me toss and turn EVERY 30 MINUTES THROUGHOUT THE NIGHT plus I AM DISABLED AND 95% BEDRIDDEN SO I AM IN MY BED ALL DAY AND ALL NIGHT and I HAVE TO HAVE SOMETHING “COMFORTABLE LIKE A CLOUD” OR I WILL GET “BED SORES” or “PRESSURE SORES”… this is soooooo disappointing!!! I would have rather spent several hundred for something better, how does someone even return something this big?!?!? Please help me. It’s even causing me shoulder pain which I never have, along with hip pain etc Read more

I had been wanting to replace my 20+ year old mattress/boxspring, but most new mattresses don’t require box springs. That meant I’d have to get rid of our king sized mattress and box spring, and also purchase a frame that could support a newer hybrid mattress. That all felt super overwhelming and wasteful. This mattress cover is the perfect solution. It gives the bed the cushiony support I was looking for and saved my older mattress, box spring, and frame from the landfill. There was a minimal odor at first which has since dissipated. This mattress cover has made a HUGE difference in the comfort level of my bed and I am sleeping much better. 5 stars! Read more

We've had the DUMOS 3 Inch Gel Memory Foam Mattress Topper King for 2 1/2 months and are very happy with it. We have a very firm mattress we purchased at Costco and this topper is just what was needed to add comfort and better sleep. We didn't notice any smell, seems well constructed, and the price is almost scary low! Read more

Very plush and directs heat away from the body nicely. It’s been a nice addition to the mattress. Sleep very well. I do have to separate myself from my partner a bit more due to our size difference~I do tend to roll into him otherwise. I put it into a cover as soon as I got it to protect it and hold it in place on the mattress. It was easy to plop on the top of the mattress and makes for a very cozy bed indeed. I notice my body refreshed and pain free when I wake up so the decompression is very nice. I don’t know how washable it is or if it protects since these are not really valid questions since it’s inside a cover. Read more

This is the BEST mattress topper I have ever bought. Game changer! It is so comfortable. I got the queen for my youngest son first, then ordered another queen for my oldest son's bed and a king for myself and husband. There is no smell past the first few hours of opening it up, and it relieves pressure points when sleeping. I would give it 6 stars if that were an option. Read more

This mattress topper made it 1 night on our bed. It was pretty comfy, but made both myself and my partner so hot and sweaty it was unbearable. We woke up soaking wet and unrested. I wish I could return it, but I wouldn’t know how to squish it back into the bag! For now, it’s shoved in the spare shower until I figure out if we try it again in the winter. Bummer. Read more
