This mattress topper has completely transformed my bed. I've bought it twice now, one for myself and one for my daughter. It fits our queen-size mattresses perfectly without shifting, and the thickness is just right for adding comfort without feeling too high or bulky. The foam feels durable and well-made, and it bounces back to shape after use, which gives me confidence it will last. I also love the smooth blue appearance—it looks fresh and high-quality right out of the box. The topper isn’t waterproof on its own, but it pairs easily with a waterproof cover if needed. Setup was simple; I just unrolled it, let it expand for a few hours, and it was ready to go. Overall, it’s soft, supportive, and super easy to use—an affordable way to make any bed or RV more comfortable!

Nice, after having a waterbed for most of my adult life, I finally bought a regular mattress, but found it to be a bit uncomfortable, so I wanted a foam topper, and didn't want to spend a lot of money, and found this one. Comfortable, took a couple of days to expand fully, not much smell to it, but I did spray some Pooph on it to make it better. It's definitely not a cooling topper, not any different than any other ones. Overall, good topper for the money, hopefully it will last a few years.

The cost worried me just a bit. But this is by far the best $55 ever spent. I have a good memory foam mattress but for some reason my hips and back ache now. Every night and morning from sleeping on it. So I decided to try this topper. Opened it up. Let it get to its appropriate size. No issues with that. No smell. Slept on it and I am happy with this topper. The first night in a very long time that my hips and back didn’t ache all night. I woke up pain free and ready to go. As far as cooling, I don’t think it does what it says. The thickness was exactly what was described in the description. It was like sleeping on a cloud. Highly recommend.

Bought it to increase the softness and comfortable of a guest bed, it works well, and sleep better. Actually I don't want the cool features because I live in a city that has to use comforter all year round. But that cooling features only works for about 15 mins, it just like a cooling ice pad that only last for short period of time. Overall I love that mattress topper. Cheap but comfortable.

So far, I t feels pretty soft and comfortable. Can’t wait to sleep on it. It’s inflated pretty nicely but I guess I’ll have to wait the 48 hrs for the full expansion.

I’ve been using the DUMOS 3-Inch Gel Mattress Topper throughout my time in college, and it has completely exceeded my expectations. The comfort level is incredible—I’ve gotten multiple compliments from friends about how soft my bed feels, and it even makes the bed look taller and more put-together in my dorm. Most importantly, the sleep quality is night and day compared to before. I wake up feeling rested and energized, which has honestly helped me stay sharp and excel in college. For the price, it’s been one of the best investments I’ve made for my college experience. If you’re looking to upgrade your bed without buying a whole new mattress, I can’t recommend this topper enough.

Highly recommend the Dumos 3 inch topper. This topper alone provides me with the comfort that I have been desperately seeking for years. It's firm and keeps me from sinking and as a side sleeper provides all the support I need. No need for a new mattress now.

Life changing lol, so much pain relief, very very comfortable and perfect on top of my annoying 8 inch spring mattress that gave me a lot of back pain. its very good value for money, took a while to deliver but worth it in the end, it is not easy to keep without sliding though, keep in mind.
