  • Love this bed!! However think firm foam bed with soft foam topper!
Item Firmness Description: Medium Size: Queen
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

  • Cloud 9!
Item Firmness Description: Firm Size: Queen (U.S. Standard)
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. ... show more

  • Decent couch mattress
Item Firmness Description: Firm Size: Queen (U.S. Standard)
So much better than the bag of coils that came with my pullout coach! I bought a pullout bed couch for company that would be visiting fairly regularly and the mattress with the couch was horrible. This mattress is comfortable and well made. There is no smell. Give decent support for being a thin mattress and I slept fairly well on it. Definitely recommend ... show more

  • Perfect Purchase
The mattress is exactly what we wanted. We started off with a complete split king a year ago. The main purpose of a complete split king (two twin xl mattresses side by side on adjustable bed frames) was so that each of our beds could move independently (head and feet can go up and down). However, I didn't like feeling like we were on different beds and in reality it felt like we were only sleeping on twin xl beds vs a king bed. I felt like I had downgraded my bed size from a queen to twins. Also, not sleeping close like before. So I looked into the top split kings and found this mattress. Oh my was it worth the purchase. Not only do I feel like I am sleeping in a real king size bed, sleeping closer together and able to raise our heads independently...the mattress is so comfortable. I've slept so good in this bed that I am mad it took so long to purchase. The bed is not too soft and not too firm. 14.5 inches is thick FYI. It didn't take long to rise. I love the zipper cover so it can be washed. It keeps me cool at night. And bonus we don't have this huge crack separating us all night. Oh and did I mention how affordable this mattress was compared to shopping at the store. This same mattress size and type can cost in excess of $2,000.00. Great buy at under $700! This mattress is just perfect! ... show more
