I am very impressed with the quality and the comfort of this hybrid queen mattress in a box. We have spent thousands of dollars on expensive mattresses only to hate them months later and can't return them. This mattress is comfortable and sturdy. It inflated to the full 14 inches in 48 hours and has no smell. Best mattress for money and even if it only lasts a couple years we for our money's worth ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Very good quality firmness is perfect *by T***A on Reviewed in the United States on October 15, 2024* I recieved the mattress opened the box took the plastic off put it on the bed . Cut the other plastic off instantly stated expanding easiest set up I ever did. The mattress is very good quality slept on it the next night. Best investment I'm made. Would highly recommend. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars This mattress is amazing. Should cost a LOT more. *by M***A on Reviewed in the United States on September 30, 2024* I got a daybed for the guest room, so then my teen wanted a new bed too. He wanted a daybed and I'd been on the hunt for a mattress. I paid 90 bucks for a basic, 8-inch foam mattress from a big box store and then more for a three-inch topper for the new daybed mattress in the guest room. I wanted something more substantial for my son, since I generally like him more than my guests.This is HEAVY and comes vacuum packed. It plumps up fast out of the packaging. It has layers. There's no single, super soft foam here, where you're feeling the bedrail slats two months after you lay on it regularly. No, this bad boy has springs on the bottom layer, so there is support. then there are several soft, but supportive layers. It is not super plushy soft. Instead, it conforms to body weight, so it is soft where a person needs it and firmer where there isn't as much push into the top layer of the mattress.I have tried 'body conforming' mattresses before to find a comfortable one. This is the only one that I've found that conforms to me specifically, then to my son, who weighs about 150 to my 110, and then to my dog who really does not like getting off this mattress, who is 45 pounds. It has hit that perfect formula to personalize itself to the person sleeping on it.And all for less than 250 dollars, versus the 90 bucks and then 40 bucks I paid for my other plain mattress and topper for the guest room. Which is fine, because I don't want guests comfortable enough to stay long anyway, but I wanted to illustrate that this mattress is pretty dirt cheap for being so darn awesome!Also, we were hit hard by Hurricane Helene. No power as I write this. We have hotspot on our phones and a little solar battery pack. Since our generator is so tiny, we can only really power the fridge and a window a/c unit, so my son and I are camping out in the primary bedroom. He has this mattress on the floor, and he has slept like a baby every single night. This kid usually wakes up constantly throughout the night, halfway sleepwalks, needs a drink or snack, goes to the bathroom, etc. He is sleeping really, really well on this, waking up feeling relaxed, and that's while we are in this stressful situation. He loves it. I love it. I keep trying to get him to trade beds with me, but he won't, so I guess I have to buy my own. Which I plan to. I do recommend this mattress for anyone who wants to sleep well and likes softness, but also likes feeling supported. This mattress is excellent quality and every person, and dog, in our household is ecstatic with it. I will not be buying one for the guest room, because then my guests would never leave.It's a great value and my kiddo's finally sleeping through the night after 17 years. I'm really excited to get my own in once mail is running again. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/662743145-king-mattress-12-inch-superior-hybrid-mattress-in-a-box](https://www.desertcart.vn/products/662743145-king-mattress-12-inch-superior-hybrid-mattress-in-a-box) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-21*
