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.

This mattress exceeded my expectations! It’s incredibly comfortable and supportive — not too firm, not too soft. I’ve been sleeping so much better since switching to it. The quality is great, and it expanded quickly after unboxing. No bad smell and very easy to set up. If you’re looking for a good night’s sleep, this mattress is a great choice. Highly recommend!

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!

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.

The media could not be loaded. I’ve been sleeping on this mattress for a week now. I bought it after reading all the great reviews, and I’m glad I did.The mattress is firm but comfortable — it gives good support without feeling too hard. I have some back and hip pain, and I already notice that I’m waking up with less pain than before. My sleep is deeper and I don’t move around as much at night. My partner also sleeps better now because I’m not tossing and turning like before. There was no bad smell when we opened it, and it expanded pretty fast. It looked flat at first, but after a couple of days it reached the full height. It feels strong and well-made — no loose threads or damage. I also like that it doesn’t make noise when we move. I like that it’s a spring mattress — it gives me the right support and doesn’t sink too much. For the price, it’s honestly amazing. We had a more expensive mattress before, but this one feels just as good — maybe even better! I’m planning to buy another one for our guest room.
