Description

What should I do if I don't like the firmness of the mattress? Our mattress firmness is tested with 1000N force for reference only. Your feeling differs based on height, weight and sleep posture. A matching mattress topper is suggested to adjust softness and improve sleep quality. What should I do if the mattress sags, deforms or loses support after use? Slight sagging under continuous daily pressure is normal, and you can use it normally if sleep stays comfy. When the mattress has severe sagging or obvious loss of support, please reach out directly for replacement solutions. How to extend the lifespan of mattresses? Rotate it every 3-6 months to avoid uneven pressure on foam and springs. Use a sturdy bed frame with slat spacing ≤5cm for full support. Use a waterproof mattress protector to prevent liquid damage and material aging.

    • Found this mattress to be Soooo comfortable!
Size: Full Style: 12 Inch
Update review- 2 months in: Well i've added a star as this mattress has been a dream. I wake up without any back pain and the profoundly wonderful desire to stay in bed! I recommend this mattress folks. Will it last 10 yrs? We'll see, but so far I have been soooo pleased. First review: Though I Found this mattress to be Soooo comfortable! I am still uncertain about it's sustainable quality after 2 weeks. Hence the 4 star rating. I bought this with all my fingers and toes crossed; who ever heard of a decent mattress delivered in a roll for 300 bucks! Well I must say that it has been very comfortable for the last 14 nights. I had developing back pain from a S--ly Postur---ic hybrid mattress that lasted me 11 years. I wish my body type also lasted that long but weight gain changed significantly as I retired and the bed gave up it's life (289lbs-uugh). Would this cheapo hybrid standup ? SO FAR YES. It is deceptively soft and yet very supportive thus far. My back pain is lessening to almost nil. My sleep is far more restful and I wakeup feeling refreshed...I know, who'd a thunk it.! My biggest problem is getting my old mattress removed, a long story! So is it worth it? I have to agree with many reviews and say unequivocally yes. Even If I get 2-3 years worth I saved I think. Delivery and setup were awkward for this single 71 yo male but doable, my old box spring support it fine. It didn't attack me when opening as others have noted and I had to sleep on it 12 hrs after opening which seemed to be fine. There was no odor, no bugs, excellent quality as far as I can determine. So I do recommend if $ is a problem. In a few months before 101day return guarantee draws near I'll post an update. Happy mattress hunting UPDATE 1/4/'21:10 months in and nothing negative to say. Ir has become even more comfortable lf thats possible! One of those rare great purchases indeed. ... show more

    • Looking Good So Far
Size: Queen Style: 12 Inch
So I have given it four stars as of right now, but I’ve only slept on it for one night and I plan to hopefully update this review periodically so that it’s as thorough and helpful as possible. Hopefully I make someone else’s online mattress shopping experience easier than my own lol. So, the bed arrived the day it was promised (which I think is more based on amazon than the manufacturer). It was very heavy, though I got a Queen. It was scary to open it because I thought I might get slapped in the face, but no one was injured in the process. Butttt it did open upside down so that was a fun thing for my sister and I to have to flip around. I didn’t measure it, but it does look like it opened to full-size pretty instantly. Overall it looks and feels like a very high quality mattress. Now for the important parts. I would say this mattress is definitely a little more on the firm side. I wanted something a little more firm, but this is pretty dense. Just about as dense as a traditional spring mattress. However, I am 4’10 and 140 pounds so I’m a little bean of a person on this mattress and know that can affect how firm I feel it. However, my more heavy set family members also said it felt a bit on the firm side. Though! That is not to say it isn’t comfortable, because it is, but it’s not gonna be that squishy soft sink into your bed feel that comes with a soft maybe memory foam type mattress, which is what I didn’t want. This has great edge support! I initially wanted a pillow top mattress, but due to the intense volume of high reviews on here I decided to go with this one. So, both the pillow tops that I have felt and this mattress all have springs for that bouncy feel of a traditional mattress (very good for adult activity, or romping lol) and a top layer of cushiony material for added softness and comfort. This mattress is not a pillow top but rather a fabric top or whatever they call it and the difference is pretty much just what it sounds like. A pillow top feels like sleeping on top of, well, a bunch of pillows. It has that plushy, fluffy texture of a pillow. The best way I can describe the fabric top is as if someone layered a few comforters or blankets on top and sewed them in. It’s not like you can feel springs or anything, it’s just that sort of texture. It definitely feels dense like thread rather than airy like the fluff material of a pillow. In conclusion, I still like this mattress very much and think it’s great quality. I will update to see if there is any improvement on my quality of sleep or back pain, it’s too early to tell right now. The firmness is something I can overlook and hopefully it will soften over the course of time and use, but if I ever do decide I want significantly more softness I think a topper would do just fine to adjust that. I will also update y’all after my boyfriend stays over to tell if it performs well for couple sleep and romping! ... show more

    • Great pick! Firm and cozy!
This mattress rules. Every Inofia mattress I've ever slept on is awesome. This one is nice and firm. It's been very stable--a mug of tea doesn't even spill if you forget it's there before climbing into bed!--and super comfy.
