  • Very comfortable
Size: Queen (U.S. Standard) Style: 14 Inch Pattern Name: Medium Firm
Very comfortable mattress, seems to be of good quality and is made well. Mattress is Not too firm or too soft. My hips seem more supported when I’m on my sides and do not wake up with hip aches. I gave it a day to decompress and plump up from being sealed in the airtight bag, it did not have a chemical smell. It seems to be a great buy so far, as it was purchased on sale. I have only slept in it for 2 weeks now and I like it so far, but if anything changes I will update the review. ... show more

  • Helps my back pain!
Size: King (U.S. Standard) Style: 14 Inch Pattern Name: Medium Firm
I’ve struggled with back pain for years, trying everything from special pillows to expensive mattresses, but nothing seemed to give me the support I needed. However, I purchased this mattress and instantly felt relief. The setup was super easy, it came rolled up in a box and took only a few hours to fully expand. I’ve been sleeping on it for about two weeks now, and I honestly can’t believe the difference. The cooling copper gel feature is no joke! I’m a naturally warm sleeper, and this mattress keeps me comfortable all night long without waking up sweaty. But the real standout for me is the support. The medium firm feel is the perfect balance as its soft enough to mold to my body but firm enough to provide solid back support. I used to wake up with aching muscles, but now I wake up feeling more rested and pain free. If you’re dealing with back pain or just want a mattress that helps you sleep better, I highly recommend giving this one a try. It’s been a huge game changer for me! ... show more

  • Super luxury
Size: King (U.S. Standard) Style: 12 Inch Pattern Name: Medium Firm
I was a bit worried at first buying a mattress off of Amazon, especially at such a good price. It seemed to good to be true, I thought it would be to soft, or to firm. Instead it felt perfect, contoured to my body, just the perfect amount of soft and firm combined. I’ve laid on so many “luxury mattresses” -Nectar, -Purple, -Puffy and a bunch more. And honestly this is up there with the best. For a very affordable price at that. It feels luxury. It took about 8-10 hours to fully inflate, it had a bit of a factory smell for some hours after taking it out of the plastic. I’ve got the 12 inch, and it fits my bed frame perfectly even though I have a bit of a mix I made myself when it comes to my bed frame. The mattress checks all the boxes. Give it a try, you won’t regret it. And if you do, it’s super easy to return on Amazon. ... show more

  • Very Cozy and comfort
Size: Twin Style: 14 Inch Pattern Name: Medium Firm
I've been using this mattress for a little over a week now, and it has completely upgraded my sleep. The firmness is about right. Supportive enough that my low back and shoulders feel aligned, but still plush enough to feel comfortable and very cozy. Setting up was easy. It came compressed in a box, was simple to move into the bed, and expanded to full size faster than I expected. This mattress does a great job at keeping me asleep well through the night, so I don't wake up. Motion transfer is minimal, so when my dog moves around, it won’t bounce awake. Overall, the build quality and materials feel solid, the support is excellent, and I’m waking up feeling more rested than before. This mattress is a serious value. I’m very happy with this purchase and would definitely recommend it to anyone looking for a supportive memory foam mattress. This is the one. ... show more

  • Surprised
Size: King (U.S. Standard) Style: 12 Inch Pattern Name: Medium Firm
Based on the mixed reviews I didn’t know what to expect. I am pleasantly surprised by the comfort and quality of this mattress. Set up was relatively easy, although we only waited about 7 hours to sleep on it. Coming from a Casper, I had low expectations. This bed is VERY comfortable and I’d say work the money. There was no smell at all, just some initial sagging in the corners that fixed itself. I will say it is not a firm mattress. I would say medium on the plushy side. I also don’t know how it will hold up overtime. We’ve been sleeping on it for 3 weeks and all is well. ... show more

  • After replacing my old mattress, this feel luxurious.
Size: Twin XL Style: 14 Inch Pattern Name: Medium Firm
Compared to my old 10 year+ Temper Pedic matress it feels amazing. The cost was exceptional and the quality feels amazing. I got the medium firm and it's just perfect for my side sleeping. I hope this product lasts as long or longer than my TemperPedic, 10+ years. I didn't smell any chemical smell upon opening. I released the vacuum sealed packaging on my adjustable bed frame so it layed flat on surface and I didn't need to lift or fight with positioning. After one month of use, I highly recommend. ... show more

  • If you find it too soft, remove the cover,flip the the mattress,put cover back on
Size: Queen (U.S. Standard) Style: 14 Inch Pattern Name: Medium Firm
It’s an affordable mattress. I thought the medium firm might be too soft at first but found that it’s comfortable. I liked it a lot initially but I have noticed that when sleeping in the same spot, after a while it starts to become less firm/supportive in that area. *After giving it a chance I’ve decided that it doesn’t hold its supportive ability like it did the first few days. Now it sinks in a bit much. It’s comfy at first but my body doesn’t like it. At this point I would go with something firmer or something that can hold its supportive ability. If your body likes firm then this one probably isn’t for you, if you like some support with a little sinking in then you’d probably like it just fine. Too bad it can’t be returned. At this point I’m considering extra firm. * For those that found it not firm enough, since the item can’t be returned, I’ve found a solution that may resolve the firmness issue. The mattress is made in sections with the bottom being the firmest, so the simple solution is to unzip the cover and rezip it onto the mattress upside down. If that’s too firm, you can undo the stitching and separate the foam sections placing the middle section onto the firmest section and the softest section on the bottom then put the cover on. This essentially gives you a combination of firmness options so you can have a better chance at finding the Goldilocks zone. Give it a shot. ... show more
