I got this mattress because I wanted something that felt solid and supportive but still comfortable to sleep on. This one nails it. The gel memory foam and pocket springs gives it the right balance. It definitely hugs your body just enough without making you sink in, and it’s got a nice bit of bounce. The firmness is just right for me. It keeps my back in line, and I’ve been waking up without those annoying neck or back aches I used to get. I side sleep predominately, but I roll onto my back a lot as well. This mattress has been good either way. Delivery was easy. It came rolled up in a box, and once I opened it, it puffed up to full size in about a day. No weird smells, The cover is soft and breathable, and I’ve noticed it doesn’t trap heat like some other mattresses. Even on warmer nights, it's not the mattress making me warm. It’s a standard queen size, so it fit perfectly on my frame. No issues. The weight limit is high enough that I’m not worried about it sagging anytime soon, even if two people (and maybe a dog) are on it. I will be sure to rotate it to be safe though. Bottom line: This mattress is a great buy if you want something firm but comfy, easy to set up, and cool to sleep on. I’m sleeping better than I have in a long time. Recommended!

After weeks of sleeping on this mattress, I can confidently say it's been a significant upgrade to my sleep quality. The combination of cooling gel memory foam and supportive pocketed springs delivers a comfortable and restful night's sleep, striking a near-perfect balance of plushness and firmness. The Unboxing and Setup: The "mattress in a box" concept was surprisingly convenient. The compressed and rolled mattress arrived in a manageable box, making it easy to maneuver up stairs and into the bedroom. Unboxing was straightforward – just carefully cut through the plastic wrapping, and the mattress immediately began to expand. There was a mild "new mattress" smell initially, but it dissipated completely within a day or two with proper ventilation. It fully expanded to its advertised thickness within the recommended timeframe. Comfort and Support: The medium-firm feel of this mattress is exactly as described. It offers enough give to contour to my body's curves, relieving pressure points on my shoulders and hips (as a side sleeper), while still providing ample support to prevent that "sinking" feeling. My partner, a back sleeper, also finds the support to be excellent, keeping their spine properly aligned. The layer of gel memory foam is a standout feature. It provides that initial plush comfort that cradles you as you lie down. More importantly, I've noticed a significant improvement in temperature regulation compared to my old mattress. The gel infusion seems to effectively dissipate heat, preventing me from overheating during the night – a common issue I've experienced with traditional memory foam. The pocketed springs are another key to this mattress's success. Each spring moves independently, which minimizes motion transfer. This has been a game-changer for us as a couple with different sleep schedules. I no longer wake up when my partner gets in or out of bed, and vice versa. The individual support of the pocketed coils also contributes to the overall balanced feel of the mattress. Edge Support: Edge support is often a concern with foam mattresses, but this one holds up surprisingly well. I can sit or lie near the edge without feeling like I'm going to roll off, which maximizes the usable surface area of the mattress. Pros: * Excellent Balance of Comfort and Support * Cooling Gel Memory Foam * Minimal Motion Transfer * Good Edge Support * Reduced Pressure Points * Relatively Quick Expansion: Ready to sleep on within a short period. Cons: * Initial "New Mattress" Smell: Dissipates quickly but might be noticeable for sensitive individuals. * Weight: As with most hybrid mattresses, it can be a bit heavy to move once fully expanded.

This mattress is super comfy and a real pleasure to sleep on. It really molds to my body and gives me firm support at the same time. I just have it on a metal frame bed that requires no box spring at all. I chose it because I was downsizing my bed to gain more free space in a small bedroom. I went from a regular queen-size bed to this double and am quite happy with it. It takes up less space, sleeps great and is easy to move around when I rearrange the room. It really provided me with a good solution to a common household problem, how to create more space without giving up comfort.

I've had this bed for a few months now to truly test its performance. This is a true medium-firm bed, in my opinion. I appreciate that it's stable and doesn't have you sinking into the middle of the bed over time. It's very supportive and even though it's not the most plush, it still conforms to your body when you sleep, but bounces back in shape the next day. I think the stability I feel with this bed has done wonders for my spine and posture. As for this bed's set up, it was quite challenging for me since I am a small woman. You will definitely need the help of another person or two. The package will be quite large and dense. When you unpack the bed, it expands very quickly. It comes with a tool to cut the packaging off of the bed, without cutting the bed itself. It smelled a little bit like chemicals to me, but it wasn't that bad. After a day of airing out, it smelled fine and was ready to lay on. I got the 11 inch full-size mattress. I recommend this bed if you're looking for something slightly soft but with stable support.

This mattress is a really nice mattress for the cost. It comes rolled and vacuum sealed in a large box, so be careful when cutting the plastic away. Once it gets air into the package, it starts unrolling/expanding rapidly and is ready to put on your bed immediately. It does recommend waiting 24-48 hrs (I think was the time frame) to allow it to fully puff up but I didnt need to do that, and was able to use it same night. It is soft and comfortable, but still firm and supportive, and it breathes so well, I havent woken up in night sweats!
