I ordered the king sized plush mattress and I honestly love it. I've been sleeping on it for about 4 months and there's been no drop in quality at all. It's not super squishy feeling, but the mattress has been great for me as a combo side sleeper/back sleeper since there's enough give in the mattress to allow for just enough sinking in for pressure relief for the back, shoulder, and hips. We had previously tried the Ghost Bed and Dream Cloud brands of mattresses and hated sleeping on those. This is a fraction of the cost and feels great on the body. Other mattresses left me feeling sore in the morning in my back or hip/shoulder areas and I would toss and turn trying to get comfortable. With this mattress I feel no pain in the morning and for the first time in a long time actually find myself not wanting to get up right away because it's so comfortable. I feel like this mattress does a pretty good job of not retaining body heat as well. This mattress is a great value and has been worth every penny. Such a pleasant surprise that it worked out!

This mattress deserves a great review! My husband and I had been traveling for 3 months after selling our home in August. We had sold our bed along with our $5000 Beautyrest mattress. Needless to say, every night was some combination of discomfort and hot sleeping on the stream of hotel room beds, vrbo and airbnb beds. Once we landed here in North Carolina, I just had to buy something to tide us over while we searched for a new home. I found this $218 mattress and said why not give it a try, how bad can it be as we were looking only for an interim solution? It arrived a few days later (which was a relief since we were using a blow up bed from Walmart). We opened the box and carefully cut open the vacuum sealed plastic and let the mattress expand. We put together our $149 frame also from Amazon and it is sturdy and solid. We put the mattress on the frame, put on the mattress cover and sheets and tried it out. It was amazing. Cool and plush at the same time. We've been sleeping on it for over a month now and it just keeps getting better and better. This $218 mattress is WAY better than our $5000 Beautyrest in several ways. Our Beautyrest mattress was hot, we had to put layers of cotton bedding underneath the sheets to avoid it getting hot. Another thing is the plush topper on the Beautyrest immediately got divets where we slept and those never bounced back. Also the Beautyrest mattress was HEAVY. This new mattress has none of these problems. It is relatively lightweight, cool sleeping and does not cave in (create divets) where we are sleeping. We feel now we were living in the dark ages with the old, super expensive mattress that we had to do so many things to in order to get a comfortable sleep. Now we look forward to sleeping on this wonderful, effortless mattress every single night! We will stay with this mattress instead of going back to the old expensive and uncomfortable sleeping arrangement from now on!

This was way better than I thought it was going to be. I needed a new full size mattress for my 10 year old. I wanted to get a good bed but didn’t want to pay the store prices so I took a chance and now want one for my bed. Great price, shipped very fast, I opened the packaging and allowed it to expand for 72 hours and had no issues with it fully expanding. It’s a very comfortable mattress! Great quality for the price!

So soft and comfortable
Reviewed in the United States on September 1, 2025 by James R De Serio Morgan
The media could not be loaded. This is an excellent mattress! The unboxing and setup were easy and only took about 10 minutes, with the mattress fully rising in about an hour or two. It is relatively lightweight and can easily be set up by one person. I purchased a 10 inch king with medium firmness. I’ve been sleeping on this mattress for about 4 months now and it still feels brand new. It was a bit firm on the first couple nights, but after being “broken in,” it’s perfect— not too firm but still supportive. It’s very cushy and doesn’t leave an impression where you slept. It stays cool and breathable throughout the night. I have no complaints whatsoever, especially for the price! I see no need to ever purchase an expensive mattress again. If you’re trying to choose between listings, this is the one! Will definitely purchase again if I ever need another mattress.

This mattress is extremely firm. I gave it a chance because I kept seeing the word “soft” in reviews. It’s not soft at all. I’ve never slept on a mattress this firm, and I don’t like firm mattresses at all. However, my friend who loves firm mattresses tried this one out and thought it was super comfortable. So it’s all about preference. If you are looking for extra firm, this would be a great one to choose. I’ll be putting this in my guest room. Nothing is wrong with it.. it’s just not for me. It arrived very quickly, and it fully expanded in 48 hours. It’s true to size and fits my full size bed frame perfectly.
