  • 2 years later and even more happy than the beginning.
I've had this bed a month now and for reference, I'm 5'10" and 190lbs. Let's touch on some common topics for my queen size bed: I prefer firm beds to the point of preferring the floor over a bed that is too soft, but this is like nothing I've ever experienced. It is extremely firm and takes a little while to conform to you after laying on it to warm it up. After a month of use though the side I sleep on more is definitely softer to the touch and responds a bit faster. I wake up feeling much better than I did on a spring mattress and usually my body feels fully rested, but I still wake up a few times while sleeping because I'm uncomfortable and I have to move completely out of the spot I'm stuck in to another area of the bed. I do experience occasional shoulder soreness that I didn't have before. Possibly from laying in the same spot too long because I tend to sleep like the dead in this bed, which is a good thing. I am a side sleeper 90% of the time with occasional back or stomach sleeping. One really nice thing is that I can sleep on this bed face down with no pillow extremely comfortable. I have to question whether a lighter person would ever get comfortable on this bed though. The heat/cool of this bed is also mysterious. I am normally a hot sleeper and sweat through the night especially on a foam mattress. Not this bed. It is freezing cold. Uncomfortably so right now since it has been cold around here. That might be slowing down the break-in/comfort level of this bed as well. The good thing is that it should be very nice in the summer time. The cool gel layer definitely works extremely well. I think using an electric blanket on it in the winter would be a good idea because it would be more supple and comfortable to hop into and get it molded to you better. Especially in the foot area where people just don't conduct much heat and your calves and feet tend to just lay on top of the mattress. Shipping was blazing fast as expected with Prime and it showed up on a Saturday afternoon by Fedex in great shape. No busted packaging as some have had issues with. One tip I have is cut a slit where the pillows are because that is the bottom of the mattress. Pull them out then flip it over and commence with the rest of the unpackaging per the instructions. Unfortunately, I set it up in one bedroom and then decided I wanted to swap bedrooms so I had to move it a day later at full size. I should have thought about it ahead of time. The cover, as shown in the picture, makes it a very elegant looking bed. Better than some $4000 springs beds I've had. The smell at first was minimal when unpackaged. Then about 2 hours into the expansion process the whole house smelled like a chemical storage facility so I opened the windows and turned off the furnace to let the house air out even though it was cold out. That worked just fine. I slept on it that night and the odor was minimal by then. To this day though, it still has a slight odor if you sniff the bed directly. Nothing that you can smell in the room though or notice when you sleep on it. I use a buckwheat pillow and have for years as it eliminated all my neck pain. I have not tried the included pillows, but my daughters use them. They claim to like them. I might try one though as the combination of the buckwheat pillow on the foam mattress is oddly uncomfortable occasionally. I've never had an issue with my pillow being uncomfortable before so maybe it doesn't work well on this type of bed. For the price involved so far I don't think you can beat this deal if you like a firm, supportive mattress. I wonder if a thinner one in the 10" range would be a bit more comfy. Once it warms up here to summer temps, I'll report back on my experience with the bed with more use on it as well. Hope this helps more buyers make their decision. Update 3/29/16: A little over 2 years in and I couldn't be happier. The one thing I did do was put a 1" foam topper over the mattress after about 3 months. This got rid of the problem of it not confirming to your body right away. The small amount of foam in the topper confirms to you, holds a little heat and actually helps the bed take shape better. I've had no issues of it sagging, getting soft or other quality issues as some have claimed. It's exactly the same as it was when I bought it and it is the only bed I can sleep on and not wake up with back pain. I still wake up once or twice a night in the same position and laying in a puddle of drool. I flip the pillow and swap to the other side of my body and sleep the rest of the night in complete comfort. I had bought a cheaper bed on Amazon for the guest room, but it is too soft I think. The wife initially liked it better, but now she prefers this bed to any others as well. We are thinking of moving to a king size though just for some extra room. My youngest daughter is super excited because she loves this bed too and can't wait for us to get a king so she can have the queen. ... show more

  • Love this bed!! However think firm foam bed with soft foam topper!
Size: Queen Style: 14.5" Plush
The one and only negative thing I would say is "plush" isn't really the best description for this bed and is misleading. The top layer dose feel soft and plush but the supporting layers are more firm. Over all giving the mattress a more medium-firm memory foam feel. Though I am very pleased with the bed as I went in knowing it may fall on the firmer side from reading the reviews (always always read reviews!!). Though this is definitely not "hard as a rock" as one user described, however it is not plush like a cloud either. Think firm foam mattress with medium-soft topper, kinda best of both worlds in my opinion. Support of a firm mattress but that nice soft feel of a plush one. :) Great quality for an affordable price and have been sleeping quite well! While I move a lot and occasionally sleep on my side I primarily sleep on my stomach and back. IF YOU ARE PRIMARILY A SIDE SLEEPER!!! I don't think this bed will be the best for you, while I find this bed very comfy for stomach and back sleeping I don't think there is enough sink for side sleepers. But if side sleeping is minimal (as it is for me) then there is no issue its not enough to cause a problem unless you spend most of the night on your side. If you are looking for a memory foam that you sink into and get absorbed by this is also not the bed for you. If you are looking for a firm supportive bed with a soft top feel (over all medium-firm) then you have found a bed that you may like! The cover over the mattress is also really nice and soft and looks durable. I did not try removing it but it is removable which makes for easy washing. As some users mentioned the box was a bit beat up, however inside the bed and pillows were very nicely sealed in plastic so the product itself was safe. I did not notice any chemical smell like others had mentioned but I also did not bury my face into my mattress. It has only been a week and a half but I am very very pleased with the bed and glad I went with a more affordable high quality bed versus an over priced name-brand mattress. I will update if my opinion of this mattress changes at all but as of right now I am very happy with my purchase! My only feedback to dynasty would be to make their description more accurate so they don't get people who are unhappy because they were expecting a softer mattress! (p.s. my two cats also are pleased with the bed. Queen is an acceptable size for me, my partner and my two cats) ... show more
