    • Good mattress
Size: Queen (NEW) Style: 12 Inch
The media could not be loaded. I'm really pleased with the comfort and quality of the 12-inch queen size hybrid mattress that I recently bought. The ideal ratio of softness and support is provided by the individually wrapped pocket coils and gel memory foam. The mattress has greatly enhanced the quality of my sleep by offering great pressure reduction, particularly for my hips and back. The medium-firm option, which I chose, is the ideal amount of firmness—not too hard, but still encouraging. It was simple to set up because the mattress arrived in a box neatly coiled up. When unpacked, it expanded rapidly and smelled fine. I saw a significant improvement in my sleep quality after a few nights, with less tossing and turning. ... show more

    • Great product for the price
Size: Queen (U.S. Standard) Style: 14 Inch

Best 300 bucks spent! Great mattress for the money. Well made and comes sealed up to open packaging so it can expand. It's heavy (70 plus pounds) so I recommend two people getting it into your house after delivery. Although with a bit of cussing and a bit I muscle I somehow managed to get it into the house because the delivery driver left it the furthest he could from my main entrance. Fairly firm and offers great support: well designed. It also has side handles so it can be moved easier. A bit of a pillow top design so it cannot be flipped - however very comfortable. ... show more

    • Decent Mattress
Size: Queen (NEW) Style: 12 Inch
Pretty decent for a box mattress, it's my first one. I have slept on it for a month or so. It feels firm, but not too firm. We'll have to see how long it lasts.

    • More of a firm mattress, made well!
Size: Queen (U.S. Standard) Style: 14 Inch
I ordered a queen 14" and Lord, lemme say that box was HEAVY! Poor Amazon delivery guy, I'm so sorry! Mattress was very well compressed in plastic, follow the instructions and you won't have any issues unpackaging it properly. It does come with a small bag with a 'safe slicing tool' and instructions inside the box. Had no weird 'plastic-y' smells or anything once the plastic was cut off to let it fluff up. It puffed up very quickly, but we let it sit 24 hrs before we put it in my daughters room. Her old mattress was literal springs and fabric at this point and so uncomfortable for her. She is LOVING the new one! It's pretty firm with good support from the pocketed inner springs. The top foam and gel layers have been great, adds the softness while still being supportive. She's had zero complaints after a week on it. Will update if anything changes! ... show more

    • Super supportive
Size: Queen (NEW) Style: 12 Inch
The media could not be loaded. Compared to my mattress that was replaced, this has been the most supportive mattress that I've owned in quite some time. It was also very gentle on the bank too. My previous mattress was only used for less than 2 years and within that time, we had so many issues with it which caused a lot of back and neck problems. Since getting this mattress, the first thing I noticed was the less and less neck pain I was starting to have. I then started noticing that even my back pain wasn't as intense and strong as it used to be. Another thing my spouse and I noticed was that we've actually started falling asleep faster and staying asleep longer. I used to wake up in the middle of the night with neck, hip and back pain and would have to take another pain pill to help me get through the night to morning. Since using this mattress, no more having to take pain pills before, during or after sleeping. This mattress fits all of our sheets and blankets so there was no need to go out and purchase new ones. Even fit on our bed frame perfectly without having gaps between the side rails and mattress. We did allow this to completely inflate before laying on it, we ended up going out of town that weekend so it worked out for us. This has truly been one of the most supportive beds I have slept on and the bonus was that there was no weird chemical smell to it either. ... show more

    • Very comfortable!
Size: Queen (U.S. Standard) Style: 14 Inch
So far so good! Proud of myself for hauling this heavy ass bed all the way upstairs all by myself 💪 I let it "breath" for about 14 hours before I slept on it. It is huge and super comfy. Has a nice bounce to it but also firm. To be fair I've been sleeping on the same matress for 14 years so anything was an upgrade 😂 But this was a great price and I really love it. I'm hoping it holds up for awhile. I desperately needed a new matress and just kept putting off buying one. My bf and I slept comfortable and he moves around a lot. Our old mateess was so wobbly and noises when he would move but I could barely tell he was moving on this one. Definitely worth the money! ... show more
