  • Great mattress
Color: Gray Suede Size: unspecified Style: unspecified
This is so comfotable!! It is the perfect amount of firm and soft. It is very supportive. It is easy to setup! It did not have a strong smell when opening like a lot of new futon mattresses

  • Best futon ever.
Color: Gray Suede Size: unspecified Style: unspecified
Firm support, but very comfortable. And will hold its shape for a long time. Way better than any traditional futon mattress. Perfect fit for our futon frame.

  • Attractive & Comfortable
Color: Brown-blueprint Size: unspecified Style: unspecified
The mattress that came with my futon felt like it was stuffed with rags. It was hard as a rock. The Kodiak Mattress is fairly comfortable, firm, not squishy. Its memory foam and inner spring construction are good for sitting and sleeping. The cover is attractive and feels durable. There's no foam or upholstery smell. It is a perfect fit for the old mattress. Amazon has many cheaper alternatives. This mattress is Made in U.S.A. My only issue with it is it is a bear to wrestle into place. I started out using it to sleep on. Then I tried to fold it into a sofa shape for sitting. It supposedly has a hinge feature to make this easy. It is not. There's a label on the bottom indicating the correct position to use it. The mattress weighs 60 pounds. The cover fits tightly so it's hard to get a good grip and pull it into place. I needed to remove it from the futon frame, fold the frame up, then while standing in front of the futon, grab the top edge of the mattress and pull it toward me while pushing it into place with my knees. This is really a job for two people. Bottom line is if you'll only change its configuration occasionally and have two people to adjust it, you'll be OK. ... show more

  • Comfier than most, relatively affordable!
Color: Gray Suede Size: unspecified Style: unspecified
This mattress is great. It comes vacuum sealed and rolled up so it is easy to move around. Once opened it takes shape fast and is ready to use in minutes. Ours looks great and is very comfy. It is thicker than other mattresses we have used but it is worth it for the comfort. This also means opening and closing the futon is harder just so you are aware. We did have one of the black decorations come off but we don't think it was the manufacturer's fault rather our excited dog. Overall this is a massive improvement to a cheap mattress while still being affordable, it looks great and was easy to get inside. We give it a perfect score ... show more

  • Very pleased!
Color: Stone Graylinen Size: unspecified Style: unspecified
After reading some negative reviews, I was very relieved to see the final product. It arrived a day early. Despite my written instructions to bring to our porch, FedEx, left the heavy package out by our curb. It expanded immediately when unrolled. I have no doubt it will conform to the 8" description. Firm and supportive, not too hard, not too soft... The linen stone color is uniform throughout; not with the subtle stripes as shown in the listing. The third picture in the ad, with the fabric alone, is a perfect match. Very rich looking! It fit our full futon frame perfectly. The back of the mattress rises nicely above the back frame. Hugging one's head, it is comfortable and relaxing - even to a tall person. It's so nice to receive what was promised, and even better, when it exceeds my expectations! ... show more

  • Sturdy, Firm, Color Disappointing UPDATE 02/06/23
Color: Stone Graylinen Size: unspecified Style: unspecified
UPDATE: I was very upset to discover that the fabric has already developed a hole after only a few months use! (Attaching photo.) I live alone, no rambunctious small children, and my rescue cat was declawed when I adopted her, so there has been nothing to cause this problem. I was forced to darn the hole using a curved upholstery needle, and now will need to disguise it with a brown button similar to those on the mattress. I can't begin to say how disappointed and upset I am. Positives: This futon mattress fits my wooden frame perfectly (I don't know if it is a Kodiak frame, but it is similar to the frame pictured in the product photo). It does not slide forward, which has been a problem with my previous futon mattresses. Since I prefer firm mattresses and furniture, I find it very comfortable. The back is tall, making it easy to rest my head, as I tend to sprawl rather than sit. The fabric texture is excellent--not a slippery surface, but a thick weave. Negatives: When purchasing an item in which color will be important, I check that color on three screens: my laptop, my phone, and my Kindle Fire. On all three, the color pictured was much lighter than the mattress actually is. On the screens, it has a slight ivory overtone. In reality, it is greige--grey beige--and rather dark. I can live with it, but will almost certainly be putting a futon cover on it eventually. The color is the reason I am not giving the mattress five stars, although the overall quality is excellent. ... show more
