I usually don’t write long reviews, but after sleeping on this mattress for a few weeks, I felt it deserved some detailed feedback. Finding the right mattress has always been a struggle for me—I’ve tried memory foam, spring-only, and even some pricey hotel-style ones, but none of them seemed to check all the boxes. This one honestly comes close. First, the comfort level is spot on. The hybrid design combines memory foam with pocket springs, which gives me the “best of both worlds.” The foam feels soft and cozy, while the springs provide real support so I don’t sink in too much. I used to wake up with a stiff back, but that’s gone now. The medium firmness feels just right—firm enough to support me, but not so hard that it feels uncomfortable. Another huge plus is the motion isolation. My partner tosses and turns a lot, and on our old mattress I’d feel every move. With this one, I hardly notice it anymore. I’ve been sleeping through the night without interruptions, which has been a game-changer for both of us. I also like how breathable it is. I’m someone who gets hot easily at night, but the surface fabric and foam layers seem to promote airflow. It actually feels cooler, and I no longer wake up sweaty, which is a big relief. Edge support is another detail I appreciate. Sitting on the side of the bed doesn’t feel like I’m sliding off, and the mattress feels sturdy all around. It gives me confidence that it won’t sag over time. Lastly, the setup was easier than expected. It came in a box, rolled up, and expanded quickly after opening. Within two days, it felt fully ready. Honestly, the convenience factor is worth mentioning—you don’t need a truck or movers to get it inside. Overall, this mattress has been a great purchase. It’s comfortable, supportive, quiet, and easy to set up. For the price, I really think it offers great value, and I wouldn’t hesitate to recommend it to anyone looking for a solid night’s sleep.

This mattress is comfortable and high. The edges are hard to sit on as they sink so be aware if you sit down in the morning to get dressed or to put on socks. This is a non-issue for me but worth mentioning for others as it took me by surprise. The color is esthetically pleasing. Unfortunately this mattress was left in my lobby in a walk up buiding so it was heavy even for two adults to get up to the third floor of a walk up building. Memory foam has been amazing for my lower back pain but it's a big change from spring matresses so be aware. Overall I love it so far, it is functional, and there is no noise from the mattress.

I didn’t know how I was going to feel with buying a mattress from Amazon that was coiled in a box and I really didn’t like the idea of not being able to try it out first. I have to say that this mattress is pretty nice. We only have the twin size but it’s comfortable. It expanded where it should I. The most important parts because I dont mind if a few the corners don’t come to full height because its on a low bunk and he’s 5 and that wouldn’t matter anyways. We will have to wait to see if it holds up for any extended period of time though!!

I definitely made the right choice in returning a different brand of mattress for this one. My lower back and hips don’t hurt near as much when I wake up. The mattress doesn’t move when I turn over and it doesn’t make any noise. I just really really really like this mattress. I’ve been sleeping on it for about a week now. I only allowed it to expand for 24 hours because I was ready to sleep on it. But no complaints.

Bought this bed for our 3.5 year old. 12 inch depth. It is perfect for him based off the price and comfort level. The full is better then the twin as there is room for mom/dad during bedtime stories. Bed just sits on the floor in his room. Low transfer of movement when exiting the bed. Would not purchase this for an adult use. Bed is not firm enough for the weight of an adult and has poor edge support. Perfect for children however! Giving a 5 based off the above descibed usage.

I am absolutely in love with my Queblox 12-Inch Hybrid Full Mattress! From the very first night, I could feel the difference it’s the perfect combination of softness and support. The top layer feels plush and cozy, while the inner coils give just the right amount of firmness to keep my back comfortable all night. I’ve been waking up without aches or stiffness for the first time in years! The mattress arrived quickly, neatly rolled and vacuum-sealed. It was super easy to unpack within a few hours it expanded to its full height and looked beautiful. There was only a very light “new mattress” smell at first, but it disappeared quickly. The quality is excellent you can tell it’s made to last. The edge support is great (no sinking when you sit on the sides), and it doesn’t transfer motion, so even if someone moves next to you, you won’t feel a thing. It truly gives a luxury hotel-level sleep experience at an affordable price. If you’re looking for a mattress that balances comfort, support, and value perfectly, the Queblox Hybrid is it. I’ve never slept better — five stars all the way! It’s very thick

I am very pleased with my mattress. So thankful it came in black. I have several grandkids and I really was not wanting a white mattress. This was perfect. I need another one but am going to have to wait a bit to save for it. I will be ordering the very same black twin mattress as I order before. Thank you Queblox for a great product at an affordable price.
