DynastyMattress 4-inch Cool Gel Memory Foam Mattress Sleeper for Convertible Folding Sofa & Couch Beds Full Size Sofa

Good quality for the price. I bought this for a used sofa my daughter bought for college. It fit perfect and is comfy. You can’t feel the frame of the sofa underneath.

It fit my hide a bed couch perfectly. Very comfortable. Much better than the original air mattress.

For the last 6 months I’ve been sleeping on this mattress in our RV pull out queen size bed and it’s so much better than any other hidabed mattress I’ve ever slept on. It wasn’t thick enough for my 180 lb husband to sleep comfortably, but it works for me at 115 lbs. After a few months of sleeping on the bed, I did begin stuffing an extra pillow under/beside my back for extra support to prevent waking up with an achy back. I would buy it again. It has held up very well and it hard to find a mattress that allows the bed to close, does not flatten out or become creased from constant folding, and the couch cushions still fit nicely with the bed dressed. It’s a really nicely made mattress with a soft cover.

I am always very skeptical of reviews on Amazon but I decided to try this mattress for my new sleeper sofa and I'm glad I looked into it and weighed out my options. This sofa mattress is incredibly comfortable. I sleep on a Sleep Number bed and this mattress is just as good!Looks are deceiving as it is a 4in to 4.5in mattress and kind of looks like a standard pillow top. It came coiled up in a box and it was "space packed" aka suctioned to be as flat as possible. It was easy to remove from the packaging and the plastic wrapping it came in.I laid it out for the night and it grew to its full size. People have complained about the odor but to me it smells like the plastic it came in, pretty standard for most things. I'd say that within 3 hours it was fully expanded and by 10 hours there was no more plastic odor. I am very happy with this as it is quite affordable. Some of the "top line" sleeper mattresses are at least $300-$500 and this one was half the price and of equal standard.You can't feel the sleeper base at all as the foam is very dense and even rolling around on it, it keeps a good shape. The memory foam springs back very quickly and helps relieve pressure on your butt and spine.I'd definitely recommend this to anyone who is skeptical about the reviews and is looking for a comfortable and affordable option for their sleeper sofa.

We originally had air bed mattress for our fold out sofa in our Travel Trailer. When the air bed split and was useless we went looking of alternatives and luckily with found this very high quality 4" mattress. It worked great for our application because we can simply fold it in have and store it behind the sofa when not using it. With our type sofa cannot leave it on the sofa then fold the sofa back up. On some home sofas you might be able to to do that.People commented on odor: I did not not notice any odor with this mattress upon opening it up. I had a foam mattress topper once that required you let it air out a few days before using it. Not with this mattress.These foam mattresses are compressed by a machine to about 50% of their size and vacuum sealed in plastic when you receive it so it will fit in a smaller shipping compartment. When I removed it from the shrink wrap I put it on our bed in the trailer and let it fully expand for a couple days. No problems at all. One person complained in the reviews that it would not fit back in the original carton. Now you know why. None of them, toppers or mattresses with go back into the original carton for the reason stated above.Only word of warning for some people; this mattress is quite HEAVY. So if you constantly have to lug it around that might get tiresome. If you only need to move it occasionally, then you'll be fine. Overall very happy.

The mattress is 3 inches not 4!On November 3, 2021 I sent Dynasty Mattress' customer service:"I do not see an option to contact you through Amazon. Based on your description, the mattress is listed as 4" thick. When I opened the vacuum sealed packaged, it was only 3", even after letting expand for several hours. It is my belief the item is faulty.The issue is however, even though the shipping is covered, the opened item no longer fits into the original box and UPS wants to charge $80 for the oversized item. Given that the product is not as described, I request you reimburse me for the item without return of product, as I don't think there is a way for you to reimburse me the $80.Please let me know of the resolution soonest."Dynasty Mattress' customer service replied a few hours later and asked for my Amazon order number and photos of the mattress with visual measurements. I promptly replied with the order number and images.On November 5, November 9 and November 11, 2021 I followed up with Dynasty Mattress' customer service and did not receive a response.On November 12, 2021, after contacting them four times, Dynasty Mattress' customer service replied:"Your order appears to be an Amazon fulfilled order. Please contact Amazon customer service.Thank you."This has been a very disappointing customer service experience. The mattress is not as advertised and Dynasty Mattress will not take responsibility for a return or refund and Amazon directed me to Dynasty Mattress. Buyer Beware.If Dynasty Mattress or Amazon is willing to resolve this issue I would be very appreciative.
