  • Relief at last

    Suffered from intractable back pain for almost two years from sleeping on a mattress that cost $1300 (without the box spring). Pain free after ONE NIGHT on this futon. No odor as some have described. The shipping department is not too concerned about packaging and protecting this 100+ pound behemoth, so the cardboard was ripped in many places and even the plastic covering was ripped. The mattress probably would have been ruined if it had been raining. "Free" shipping. Still no regrets. There is no reason to go to a mattress store ever -- futons are the way to go.

  • Finally got the mattress that i can use

    Finally found the mattress on which i can sleep for 8 continuous hours without turning and trying to find the right position. Best mattress for people who like firm style.

  • no support at all.

    I had couple of futon mattress and they were extremely good for my back, (bought from King Futon in san jose, california). After I moved to Texas needed another one. Bought this one but highly disappointed with this product. It says 8 inch but after using couple of days it became 3 inch. Does not hold it shape, very soft.

  • Good for Asian Indian people

    I am from India and did not like the spring mattress used here in America, I was desperately looking for simple cotton filled mattress. I am lucky to find it here. Its just like the mattress we sleep on in India. Very firm at the same time soft. My wife just loves it. All my friends also liked it, they told me they also plan to buy it.

  • Great Value, Comfortable Firm Mattress

    The mattress arrived in 4 business days using the included standard shipping option. The mattress feels different than a standard mattress because it is not a standard mattress. As in the picture, the mattress is not completely flat, there are indentations which are part of the design (I assume this is part of the scaffolding that holds the cotton in place). Things you should know: The mattress did not come vacuum packed. It arrived wrapped in plastic wrap. It takes two people to carry the mattress. I decided to give this mattress 5 Stars because it is a good product for a fair price. That said, I think most people would prefer a standard mattress for regular sleeping. I would not suggest using this as your everyday mattress unless you like the feel of a cotton mattress as opposed to a standard mattress.

    As I had figured, this mattress is actually more like 5-6 inches. I have no problem with that in the least. It's still very comfortable, plush, and I haven't slept better in years. I have this mattress directly on the floor, like most other reviewers. It is VERY heavy. You really need 2 people moving this thing. I was able to slowly drag it in the box all by myself to my bedroom after the FexEx driver wouldn't step foot in my house, due to liablity issues, apparently. The mattress is every bit of the 100lbs the listing states. It comes rolled up like a taquito and there are plastic straps holding it in place. Then it's covered in stinky plastic wrapping. And then there's the outer box... also wraped with plastic strapping. The box was beat up when it arrived, but the mattress was completely unharmed. I can't imagine the trip the dang thing had across the country being that heavy and huge. Oh and it was delivered exactly 4 days after my order, and I didn't even choose expedited shipping. That was awesome. Anyway, once out of the packaging and unrolled I immediately regretted not rolling it out exactly where I wanted it to be. When it's all sprawled out, moving it again seriously does require two people just because it's awkward, and did I mention... HEAVY! Oh and the smell. I expected that too based on other reviewers. The smell lingered for maybe 2-3 days and then it was just fine. It smelled chemical-like and almost cedar-like, it was weird. But no smell in the least now. Oh and I actually haven't gotten out the tape measure to see exactly how big it is, but a standard king fitted sheet doesn't fit. I'm going to end up getting a flat sheet and sewing some elastic on it to make do with what I've got. In spite of all this, I wouldn't have any other bed. This is the ultimate. I no longer have back pain, it's extremely comfortable (firm, for sure, but supportive), and looks great. I highly recommend it. For the price, it just cannot be beat!

  • It works--so far!

    I have been sleeping on the floor using a futon mattress for 25 years. Recently, I decided to upgrade from Queen to King size. I saw this futon advertised through Overstock and the price was reasonable--especially when you factor in SHIPPING!!! Although the futon appears well made, I am not sure how long it will keep its structural integrity because the cotton doesn't feel packed very tight. So for those using it on a futon frame this will be fine. I'm not sure how many king sized futon frames there are in the world though. I also ordered a 4inch memory foam pad for the futon, which makes the whole setup extremely comfortable and will probably keep the futon from packing down. I will try to remember to update this review in a year or so to see if the futon keeps its shape. As of right now, I'm sleeping wonderfully!

  • Great value for ppl who like extra firm mattress

    Arrived in 3 weeks in California. Very heavy over 100 pounds. After unwrapping smells a bit of chemical for couple of days. Smell goes away in a week. Very firm, just like cotton mattresses in India. My back troubles went away within a week. Bit too firm for people who sleep on the side. Great for back and stomach sleepers. Need to rotate the mattress in first few weeks every 3-4 days to even out the cotton filling.

  • i saw one review about the size - says its actually 4 inches thick . Is it true? we are looking for 8 inch thickness.

  • Can this futon mattress fold easily? we want to use it and be able to put it away in a closet folded like a a hot dog bun?

  • I noticed that one of the reviews states that the mattress smells like formaldehyde. Is this true? I'm looking for a mattress that my children can sleep on and I worry about any fumes. Please respond.

    • The item is vacuum sealed in a box, so some fumes may be there. You should allow several days for the item to return to full loft and smooth out. It should definitely not have any smell to it.
