Medium plush mattress that feels expensive but isn't
Size: Queen (U.S. Standard) Set name: 10In
I've been needing a new mattress for a while now and was about to buy another spring coil one but decided to give this a try. It comes in a 1×3 foot box that one person can maneuver fairly easily. Not too heavy to lift at all. Inside the box is your rolled up mattress wrapped in plastic and vacuum sealed, so make sure you have it positioned on your bedframe before unleashing it. This thing is awesome! It expands fully in less than two hours, though I gave it a good half a day before using it. I went with the 10" thick model and it feels so comfortable! Firm support but still plush. It's made of memory foam material that stays relatively cool throughout the night. Fits my queen bed frame perfectly. Also, my husband can toss and turn all he likes but I don't feel a thing on my side of the bed which makes for a quiet restful night's sleep. I'm never buying a spring coil mattress again. This thing is perfect! ... show more

The Most Comfortable Mattress Ever
Size: King Set name: 14IN
This is the most comfortable mattress I’ve ever had! It has the perfect balance of being firm but still soft and comfortable. It doesn’t make any noise when moving around, which I really love. I sleep so much better on it and I’m extremely happy with this purchase. Highly recommend

10/10 would recommend to anyone wanting a balanced, restful night’s sleep.
Size: Full (Small Box) Set name: 12"
This 12-inch full size hybrid mattress saves my sleep! The individually wrapped coils offer just the right support for my back, while the top memory foam layer contours gently without feeling too sinky. It arrived vacuum-sealed, expanded fully in 4 hours, and had almost no off-gassing odor. I’m a side sleeper and it keeps my hips and shoulders perfectly aligned—no more waking up sore. The edge support is surprisingly solid too, so I don’t feel like I’ll roll off when sitting on the side. For the price, it’s way better than the overpriced brand I tried before. ... show more

Quality product - Be aware of damage
Size: Queen (U.S. Standard) Set name: 10In
I was disappointed with the distributor because my mattress arrived with a stain and tear on it . It was freshly unbox , plastic unraveled and inflated then I noticed the stain and rip . I live in The Bahamas, therefore shipping it back would not be as simple or easy for me and super expensive. Other than that , the comfort of the mattress is exactly as described and would be considered worth the price. I toss and turn all night and although the mattress does prevent that it truly helps to support my body with the movement . I can say I’ve woken up feeling better even if the amount of sleep is short. For those curious like I was if the mattress would suffice without a box spring , a box spring still helps. ... show more

Comfortable mattress and good value
Size: Twin(U.S. Standard) Set name: 6In
I waited a bit before leaving a review because I wanted to see how the mattress felt after actually sleeping on it for a while. When it first arrived, I opened it and let it sit for about 24–48 hours so it could fully expand before using it. The mattress expanded well and fit the twin bed frame properly. The firmness is what I would consider medium—not overly soft where you sink in too much, but also not hard or uncomfortable. It has enough support for everyday sleeping, and the surface still feels comfortable. For the price, I think the quality is better than expected. It works well for a twin bed, especially if you’re looking for something practical, comfortable, and reasonably priced without spending too much. ... show more

I am completely happy with this mattress!
Size: Twin Set name: 6In
Bought this well made 6inch mattress to lounge on outside in my private garden and its perfect! I put a 3 inch foam topper in it, closed it up in a movers plastic bag, then zipped it up in a fully inclosed twin size waterproof mattress pad. Zero crinkle noise! And so comfortable! Thanks Avenco!
