  • Honest review after 2 months
Size: Queen Style: 14 Inch
I've been sleeping on this bed for 2 months now and I've never slept better. I have back and hip problems and was constantly waking up throughout the night, waking in pain and tossing and turning never getting a good night's sleep. I can't say this mattress ended all that but I it has made a huge difference. I am able to sleep through most nights and don't wake up in more pain than when I went to bed. I love that my partner isn't constantly being woken up on my bad nights from me moving around. I love the added height of the 14 inch mattress but the down side is making sure the sheets I purchase have deep pockets. Delivery and setup were absolutely fantastic. It took 2 days to deliver and absolutely NO funky smells when it was opened. I was surprised at how quickly it took shape and was almost back to full size by the first day. The edges and corners took about 2 days to get to the full 14 inches. It is a bit firmer than I thought I wanted but after 2 months it's like sleeping on a supportive cloud! I was so impressed with the quality and look of the mattress. It was far beyond what I expected for the price I paid. It's so far WAY better than my previous matter that I paid over $1000 for. This bed is worth way more than what I paid. ... show more

  • Good Quality and made very well
Size: Queen Style: 14 Inch
I purchased this mattress back on April 12, 2025, and received it very quickly. Removed from the box and placed on bed so that it could inflate and waited the 72hrs as instructed before sleeping on it. It took me 45 days to see whether or not this mattress was for me, and I can say that this mattress is very well put together, strong edges when sitting it doesn't sag as most and it has handles which you don't find on mattress today. it's a good quality mattress and it helps with back issues and it's for sleeping on your back, side or face. It fits well on to most frames. it's a great value and yes, it is heavy in weight but sturdy. It will take some getting used to but after sleeping on it you will be able to tell if this mattress is right for you. I gave it a 5 star because it is a great mattress but 4 stars only because it wasn't a fit for me and I'm saying that it wouldn't be a fit for the next person because everyone is different and have a different opinions and style of mattress they prefer I'm just saying for me I prefer a flatter mattress that doesn't have a lot of cushy puffy pillow pockets, but all in all the mattress is a good quality mattress and built very well and if you like puffy cushions on our mattress then this will be the mattress for you. It's a medium firm mattress not soft and not to hard just in the middle. I would recommend this mattress to my family and friends. ... show more

  • 5 stars!!
Size: Queen Style: 12 Inch
Love this mattress! I plan to buy another for our guest room. It’s not super heavy, nor is it too light. Has the perfect amount of firmness - where it offers support, but isn’t like sleeping on a board either. The fabric and stitching seems to be good quality too. It’s also a great price, especially when you compare it to the “big name” mattress companies. We had a name brand before and it was the terrible. My husband wanted to go another big brand again. We compromised, decided to try it and if we didn’t like it we’d put it in a guest room since they don’t get used all the time. We both love it, so happy! ... show more

  • Easy delivery, good mattress for the price, supportive.
Size: Twin Style: 10 Inch Plush
The box arrived mostly intact, a little torn but I expect that for a soft item in a heavy box. It's wrapped in a giant piece of cling wrap, and you just pull the wrapping from one side where it starts, and unroll. At the end of the cling wrap, the bed started to unfurl itself slowly. It was still wrapped in a heavy duty bag. I cut the corner of the bag and it began to fill out quickly. I really wish I had recorded it, it was so satisfying, you can hear the coils stretching, it sounds like the mattress is taking a huge breath. It was a regular twin mattress in about 2 minutes. The best thing....no funky chemical smell. I have gotten some weird toppers and mattresses before, and the memory foam smells for awhile. No such issues with this mattress. It smells fine, or like nothing, and was packaged well. I laid on it as soon as it stopped breathing, and it's just a regular mattress, it's crazy. The foam on top isn't as thick looking as it is on the picture, and the mattress is quite firm to me, but it's not for me, so that's fine for the person using it. It's sturdy, no rips or tears or cheap looking threads hanging off, and there's handles on the sides. The corners don't have a ton of support, and you can push on them easily, I haven't just sat on the corner yet. You can see the wrinkles in corner in the photo where it easily scrunches. The bed overall as you lay on it is very supportive, though. I imagine there's no easy way to return this once it's out of the bag, so plan on investing in this mattress to keep it. I would give it 4.5 stars but since I can't, it's 4 since it's not perfect, but I'm pretty happy with it overall. I just wish the memory foam was a little thicker like in the advertising photo. Otherwise, a great experience for buying a mattress that comes in a relatively small box. ... show more

  • Get you this bed !
Size: Queen Style: 14 Inch
I just bought this ! I saw all the positive reviews and went for it, best decision. It was an amazing price with taxes it was under $300 feels exactly like one we bought that cost over $1000 + medium firm mattress I love the feeling of not sinking down into the bed. I got the Queen 14 inch it’s super huge but amazing ! I don’t feel my partner moving around too much at night, it is pretty heavy but it’s well made. My whole body feels supported. I literally just opened it today and it bounced up really fast . I had the best nap of this week ! I could not wake up ! Super pleased with the purchase! ... show more
