Milliard Trifold Mattress, Queen Size, 4 inch, Portable Foldable Mattress Queen with Medium Firm Foam, Washable Cover, Tri-Folding Floor Bed, Fold Up Guest Bed, RV Travel, Camping, 78" x 58”

We got this fold up bed to use when we stay at relative's houses when there is not enough beds. This bed is VERY thick and comfortable. A twin size sheet will fit on it. We have used it a bunch and it has not started getting flat. It still is very thick and soft. I will say it is bigger than I thought it would be which is good and bad. Good for the person sleeping on it but not good when we could barely fit it in the car. We now leave it at my in-laws and use it every time we stay there. I did a lot of research before purchasing this bed and I am super satisfied with it. We also bought the cover/case to go with it.

Bed is easy to setup and comfortable for all sleepers. Be mindful that it is low to the ground, so it may not be great for those with mobility issues. It is collapsible, but only to a third of the mattress so it will take some space for storage. Currently using it on a cross country trip and it’s holding up very well. overall great purchase for comfort and price.

This came in clutch for visitors. I asked my son how it felt and he said "like feather". He also stated that the he did not notice that this was a fold up while sleeping. Highly recommend.

I am severely chemically sensitive and only had to air this out for a couple weeks...unlike most mattresses that take about a year. I figured if I bought a new one every year, it would be about the price of a typical mattress. I have a hard time sleeping on mattresses that are soft and this one hasn't been too bad. It did get softer after about a year, unfortunately and is the reason for it losing a star, but I'm tempted to never go back to a normal mattress because this is so might lighter to move. I can get the sheet on and off this much more easily than a regular mattress. I lay this on a 2" thick gynastics mat, which insulates it from the cold floor and has prevented mold on the bottom. I also have a waterproof mattress cover on it, which keeps moisture from getting into it, so I t think that has protected it from mold also. I have back issues and so I may go for up to 2 weeks at a time without folding this up or moving it at all, so I have been very grateful for the lack of mold, especially considering there was a roof leak in the bathroom and so I've struggled with a lot of back mold in the bathroom toilet and sink, but not once on this mattress, my sheets, or exercise mat, despite not moving it. I would recommend replacing it every year if you don't want it sagging in the middle or if you are light. I weight about 180 lbs and I bought the 4". If they made a 3", I'd try that as it might not sag so much as it gets older. The area where it folds is uncomfortable if your hip is over it, so I just slide down a bit and it's been fine. Overall, I'd recommend this to chemically sensitive people, to older people who have a hard time managing getting sheets on and off a larger mattress or moving one around. I love being able to stretch out on the floor, but hate getting up and down of the floor, especially in the middle of the night, so I might just get a platform bed at some point that's larger than my mattress to give me that extra space, but not have to get up and down off the floor.

This is very comfortable! It smelled a bit for a couple of weeks but has been fine ever since.

I just bought my second one! I am 74 years old, and I have been sleeping on the floor on this mattress since 2019. I share a one-bedroom apartment with my granddaughter who has the bedroom, and so I chose this mattress to use as my bed in the living room. I absolutely love it! It is super comfortable, and during the day it morphs into my coffee table/ottoman for which I have a beautiful cover. No one ever believes it is my bed! As all mattresses sag with time, this one lasted for 5 years using it every single night, and I slept so comfortably. It's not just for guests, but if you're buying it to use as an extra bed for guests it should last a lifetime! You won't be disappointed.

The full size Milliard trifold mattress proved to be amazingly quick and easy to set up. I have attached a picture to show the starting size when still in the box. Once opened, we unzipped the mattress cover as suggested by Milliard and it reached its full size within 1-2 hours. We purchased the 6 inch mattress and early sleeping results have justified that decision. By the way, we decided to place this mattress on a foldable frame (18 inches high, also available in 14 inch size, made by Amazon Basics that we assembled in literally 1-2 minutes. As shown in a second photo, even the shipping box proved useful to our cats. We were so pleased with the Milliard trifold buying decision that we just ordered a twin trifold mattress in the XL size that is 78 inches long.

Using nightly for past 6 months, still holding up this foam height is definitely more comfortable and it has about the right amount of stiffness.
