Question: How firm is this bed? I had a foam floor mattress before but it got soft too quickly. I would love something to be firm and stay firm!
Document: I originally purchased this for use when my son comes for visits. I actually ended up sleeping on it when my dad had to stay at my house for about 1-1/2 months. I was a little concerned, because I had recently injured my back and it was still an issue. But lo and behold, this futon mattress (and I just used it on the floor) proved to be as comfortable or more so than my regular bed.
Now this mattress for some people may feel hard. To me is fine, I wanted something that feels like a flat surface, like if you are sleeping on the floor, and this mattress does exactly that but with some added  padding. Plus if you want more padding then you can buy two, and make it to double in thickness.
We use this with a 4&#34; think foam bed and it is excellent -- more comfortable than the expensive spring mattress on our regular bed. Great purchase that we have recommended to others.
This bed for sure firmer than your spring bed or your memory foam bed. But that is exactly what I expect it to be! You will have easier time in the morning to wake up and you won't feel tired or unrested.
I like the bed. For the first two weeks, it was great. But it went flat pretty quickly, and now barely gives us coverage. It can be fluffed, but that gets annoying doing it daily.
This futon is VERY comfortable! We bought it for guests but we love it so much that we'll use it on our bed as extra padding -- I sleep like a baby now haha. 2 things though: I wish it had more padding, but the price and quality for this futon is right so no worries, and I thought it was gonna fold and not take too much space -- not the case, you gotta roll it and store it like that. Otherwise, GREAT BUY!
Having guests but no extra bed? Don't worry, this Queen size futon is so comfortable that anyone will get a good night sleep over it. We also use it for our daughters when we go out camping. Extremely easy storage and opening. Love it.
This is a good mattress that is fresh and has the added advantage that it does not sink. We were looking to replace our spring coil mattress, which we had to replace every couple of years because it always sunk with my husband's weight, so we bought a memory foam mattress, but it felt terribly warm. The foam mattress felt like if you sank into a warm oven. For me that was extremely uncomfortable. We returned it to the store after having it for about a month.
this is by far the best futon that i have owned. typically i have gone for the traditional couch futon. i decided on this cause i already have a nice couch, better then any futon one. this floor matress is great because it is only slept on, not sat on like the couch style and flattened out in odd spots and becomes lumpy. this one does flatten down but it is still super comfy, no lumps, and soft.
This is an inexpensive futon and for the money, it is okay. It is also smaller than the dimensions stated by a couple of inches on both sides. This is important if you are counting on each of those inches.The fact that it does not come with a removable cover took my rating from 4 stars to 3. And regardless of what anyone says, you cannot remove the cover without ruining the futon. The shipping was outstanding. I received it very quickly.
Answer: Is very firm and will not get soft. It is made from layers of cotton, with a little bit of foam. The cotton tends to get hard, that is why it needs to be rolled on a regular basis. This is a Japanese style mattress. To me is perfect and cool, for my husband, he says, is way too hard. Not bouncy at all.
