Description

What main function do pocket coils serve on this mattress? Individually wrapped pocket coils separate body pressure and cut movement vibration, so partner shifting won’t create sleep disturbance all night. What’s the core function of CertiPUR-US foam materials? Certified low-VOC foam eliminates harsh chemical odors and hidden fiberglass, creating a safe non-irritating sleeping surface for long daily use. Why should I buy this hybrid mattress instead of basic foam mattresses? It combines cooling gel foam and silent pocket coils to solve heat retention and partner movement disturbance common with all-foam mattresses. What bed frames work well with this mattress? Compatible with platform beds, slatted frames, box springs, bunk bed bases and flat solid floor foundations. What purpose does vacuum compressed packaging serve? Rolled compact packaging simplifies door-to-door delivery and easy transport through narrow hallways, stairs and small apartment entryways.

  • Perfect blend of firmness & softness.
Size: Full Item Thickness String: 10 Inches Set name: Hybrid Mattress
I didn’t had hubby expectations buying a mattress from Amazon tbh but the quality was surprisingly high. It has a perfect blend of firmness & softness, it was extremely easy to set up because of the weight and it inflated pretty quickly. I’ve been using it for a few days now and the support on it is amazing. I’d compare it to one of those big expensive brands. ... show more

  • Great bed

Love the bed. New to hybrid beds it's a little soft on the edges but otherwise it's great

  • Full size mattress
Size: Full Item Thickness String: 10 Inches Set name: Hybrid Mattress
This full size bed is super comfortable. It’s very well made for the value. It is as thick as described. I waited to write my review until I was confident enough it wouldn’t be temporary. I did also purchase a topper and a pillow top cover to enhance the comfort.

  • Very firm
Size: Queen Item Thickness String: 10 Inches Set name: Hybrid Mattress
We bought this mattress in January and it seems to be good quality. My only complaint is that it's a little too firm for me, but that might be what some people are looking for. I like the color of the mattress and it was convenient that it came packaged in a box rolled up and was delivered instead of having to find a way to haul and move a mattress. If you like a really firm mattress, I'd recommend this one. ... show more

  • One of best mattresses I have ever owned
Size: Full Item Thickness String: 10 Inches Set name: Hybrid Mattress
I can’t say enough good things about this mattress—it’s honestly one of the best I’ve ever owned. As a side sleeper, I usually wake up with numbness or soreness on one side, but that completely changed with this mattress. It perfectly cradles my body and provides the right amount of support, so I wake up feeling refreshed instead of stiff or sore. The hybrid design is a game changer. The combination of springs and memory foam gives it the perfect balance—it’s not too soft and not too firm. It feels supportive without being hard, and comfortable without sinking in too much. I’ve been getting some of the best sleep I’ve had in a long time. Highly recommend! ... show more

  • Great mattress, but too firm
Size: Full Item Thickness String: 12 Inches Set name: Hybrid Mattress
This looks nice, but I was looking for something but softer this was just as fine as the one mattress I was getting rid of, so I sent it back now if you like a Firm mattress then this would be a great mattress for you. I bought a soft mattress hybrid and it’s very comfortable however, it doesn’t have any edge control and I’m always slipping down or almost falling out of it. This mattress has excellent edge control, and you won’t slip off. The three star is just because it was just too Firm other than that it seems to be a quality hybrid mattress. ... show more
