Adaptable green tea memory foam hugs the body and promotes freshness for comfortable sleeping all night long.
  • Multi-purpose: With a gel soft memory foam layer and a polyurethane foam support base, this sofa mattress is vastly more comfortable than traditional sofa mattresses that either are flat mats or have springs.

  • Machine Washable: This plush sofa mattress comes equipped with a removable and washable zipper cover, machine washable & tumble dry low, so cleaning is a breeze. Non-slip fabric on the bottom keeps the mattress confined to the sofa bed.
  • OEKO-TEX Certified: The material used in this Quilted Sofa Bed Mattress has passed the OEKO-TEX certification. Our mattresses have a 10-year warranty, if there is any dissatisfaction or problem, please feel free to contact us for support, we will reply as soon as possible.

  • Soft and comfortable
Style: 12 Inch Cool Cover Size: King
Good mattress. Came quickly, inflated quickly and very cost effective.

  • Suitable mattress!
Style: 10 Inch Size: Queen
I see now why some consumers complained about the mattress sliding.. because it does, lol! It can help to have more grip on the underside; help it maintain it's tenacity. It is supportive unless, of course, you're bedridden. Then it may leave a dent but that's all mattresses, especially foam! It captures your body temperature and even the room's temperature, meaning there's a great mixture between the two. It's size is enough to hold an average woman, man and about 2 to 3 young children, so about a Queen. It's shape shapes with you and your body! No stiffness or soreness of the body, as long as it stays healthy and lively. Meaning you don't lay on it all day. So, those who had surgery, are overweight or are pregnant, you may have to adjust and move around on it after a few months. ... show more

  • Worth Every Dollar
Style: 10 Inch Size: Queen
It arrived in 2/days, excited 😊. It was well packaged, & new. I added it to my new bed frame, & in about 1/hr. I had a well queen sized, thick, firm, value for your money, mattress out of a box. It’s so, comfortable, & the expansion is, Great. It’s a must buy šŸ˜

  • Very firm!
Style: 8 Inch Size: Full
Firstly, I have never purchased a foam mattress before so I cannot compare this mattress to others in its category but I will give my honest opinion here. I purchased this mattress for my one year old. Positives: This mattress had zero smells when it opened. I opened it midday and it was completely done inflating by bedtime and I felt comfortable putting it in my child's room by night time. The quality was wonderful and it is very light. The cover was a soft material and it had great quality foam with all the proper certifications. I was pretty happy with it upon opening. Subjective: This mattress is very firm. It does not have the support of a firm spring mattress since there are no springs. It would be like putting a memory foam topper on the floor - you have that small amount of give and it is very firm below that. The top two inches are that type of memory foam that sinks as a warms up so when you roll over at night you aren't immediately comfortable and if you have any back or hip pain and need a firm mattress, I would recommend looking for something with springs - hybrid mattresses are my favorite. The 8 inch may also be just too thin. My understanding is that the thicker mattresses have a thicker layer of the memory foam. I personally didn't mind the firmness so much, although, I didn't really love the feeling of shifting in the night and this is not something that would have worked for me in pregnancy as my hips got pretty sore from laying on my side all the time on a latex mattress - this would have been much harder on me. Regardless, I purchased this for my one year old but, unfortunately, he flipped and flopped and woke up frequently for a week before I traded this mattress for the one in the guest room (a hybrid mattress), which he slept completely soundly on. I decided to return this mattress and search for a hybrid, which will hopefully serve us better. This company did try to give me a 50% return because they could not take the full sized mattress back but I told them, within the 30 day return window, that was not acceptable. They gave me my money back but left the mattress for me to keep or donate, which was very nice of them. Four stars for quality and customer service but this mattress was unfortunately not for us! ... show more

Style: 10 Inch Size: Queen
The mattress is very easy to setup. Expands soon as you you take it out of the vacuum bag. Very comfortable and supports your body in any position. Overall, it's worth the price.

  • REALLY HARD
Style: 10 Inch Size: RV King Size
I don’t know if I was sent the wrong firmness or I misunderstood what ā€œmediumā€ was but our mattress is REALLY hard. If it was easy to return I’d be returning it but I can live with it since it is much better than the mattress that originally came with our camper. It does seem like it’s of good quality and it didn’t have a smell like others stated. Hopefully, it’ll ā€œbreak inā€ and not be so firm. ... show more

  • Super comfortable, no foul odor
Style: 10 Inch Size: Queen
Arrived vacuum sealed in heavy plastic. Unfold onto bed and carefully use scissors to cut open the plastic. Allow a couple of hours for the foam to expand with the windows open to vent out any chemical smell that might expel. At least 4 hours is needed to be sleepable, but the instructions state 24 hours for full expansion. I slept for 3 days on it and it was very comfortable for both my wife and I. Neither of us noticed any real chemical smell. ... show more
