Description
The surface is made of cloudy quilting made with 3D jacquard tech, which creates an elegant design and provides a breathable surface. It’s woven with gold trim and has some interesting details when you look closely. Usually, we listen to our customers and then design our mattresses. Comfort, hardness, material, color matching, durability, and finally it becomes the one you see. We have used mattresses ourselves for many years and it is important to us that we ourselves as consumers find them great. As a manufacturer with many years of experience, we are sure it is unique and better than average products. It comes with additional surprises besides solving normal problems, which you'll discover as you use it.

I absolutely adore this mattress. It’s the best mattress I’ve ever had. I give it a perfect 10 out of 10. It eliminates all the issues I had with my previous mattresses: no back pain, no sinking, no tossing or turning, and no motion transfer from my partner. I’m thoroughly satisfied with it!

This review is for the Full Size Mattress, 8 Inch Gel Memory Foam Hybrid Full Size Bed in a Box, Full Bed Mattress for Pressure & Pain Relief, Certipur-US, Motion Isolation Pocket Spring, Edge Support. For a long time I wouldn't get one of these newer style mattresses as I just wasn't convinced they were a better choice over the traditional seperate box spring and mattress sets. And I had no worry about it for a long time until we needed to get new mattresses. So since that time has arrived and I was fortunate enough to get this in my offers I grabbed it, and I must say I'm happy I did! I had also recently gotten another like this that's thicker, which is fine for me. I like this is only 8 inches thick as we like to have our beds raised up on risers for the added underbed storage spaces it provides. I got this for 1 of our spare bedrooms when family visits. But do not mistake only being 8 inches thick that it can not do it's job of providing and promoting a supportive comfortable restful night's sleep! This is as well made a mattress as any I've ever looked at in any mattress/furniture store! And it would be much higher priced in a brick & mortar store. Do yourself a favor and save some money! This is a beautiful mattress too! The quilted med firm top is fantastic, providing support with cushioning. And let's not forget the individually wrapped pocket coil springs with extra support around the edges, which is really nice so it doesn't collapse on you when you sit on the edge of the bed or if you like to sleep near the edge. And all the layers of foam in between. Personally I sleep alone, so I can't speak as to whether a bed partner would feel motion by another, but I can say this is not a wimpy mattress weebles and wobbles... Stitching is excellent throughout the mattress. So this comes vacuum sealed rolled up, I'm amazed they can do what they do with these! Be careful cutting it open, unbox it in the room you want it in on the bed! Give it 2 or 3 days to fully expand for best results before sleeping on it. And this is heavy weighing in at 51 Lbs, os you may need help moving it. Speaking as someone who has a very bad back, if you have issues too, this euro top hybrid mattress is worth giving it a try to see if it helps you! Regular price $ 189.99 per the listing, which I think is a great pricepoint!

I have used nothing but full memory foam beds for the last decade so I know the pros and cons of owning one. It was time to toss out my regular mattress so I wanted to pick something that was a little different to see if would be better for my sleep. I was surprised to find out you could get hybrid beds with memory foam and springs that will ship in a box so I just had to try this one out. This arrived in a box that I was able to carry and place on my own so I didn't need to request anyone else to help me. Once you take it out of the box it has instructions and a tool to make sure you get it right on the first try. I was able to unfurl the mattress on my own too so I was pleased. After you get the plastic off the mattress starts to expand very quickly. The bed is nice and airy and didn't feel like a brick. The top has a very nice pillow like feel while to lower portion has all the supporting structure. It was a little odd using springs again but these are the springs you got in beds of yesteryear these are a new design that won't poke you or feel stiff in certain spots. I am very happy with the feel and comfort of the bed and have spent enough nights on it to make a complete judgement. The only thing I did not like is that it is pretty squeaky. When you get on the bed and any little movement you make will result in some squeaking. I have gotten used to it for the most part but I get complaints from the others in my house about the noise.

We ordered this mattress in a full size for our guest room. The height of the mattress is a good size and worked well on the bed frame we have without a box spring under it. The mattress is a decent thickness and has a very comfortable cushion top. Although you normally have sheets on the mattress, it does look very nice when there are no sheets on the bed. We have had a few guest sleep on it so far and they have all said it was very comfortable. For the price this is a very good mattress and should last many years. The only thing I would add to the mattress is handles. Other mattresses I have owned had handles to make it easy when you need to move or adjust the mattress on the frame. Our mattress did not have any handles. Overall I am very happy with this mattress and I am glad we ordered it!

Very nice well made & comfortable 12in full size gel memory foam hybrid mattress. The mattress arrives in a box with air tight packaging, once you release the mattress it will take up to 24hrs to fully expand to its normal regular which is 75” L x 54” W x 12” thick. The mattress has a good look & design with dark blue borders with gold/yellow trim detail & a white soft comfortable firm mattress top that is a hybrid memory foam & density foam material. The mattress is definitely comfortable to sleep on with a good nights rest, the current price listed is a fair value for this full size & thickness.

I love this bed. I have chronic neck and shoulder pain and my old mattress would make me wake up stiff and pained. This mattress is comfortable, cool, and helps relieve my pressure to give me a solid nights sleep. I like that its not just a memory foam or spring mattress but instead gives the best of both worlds. I find memory foam can be either too firm, or excessively soft. Spring mattresses have pressure point spots that always make me achy in the same place in the mornings. The combo of both on this, PLUS individual pocket coils make this mattress a dream to sleep on. I've slept on mattresses that cost multiple times what this one does and felt disappointed. After sleeping on this, I dont want to go back to spring only or memory foam only mattresses.

The 'medium feel' is spot-on: not too hard, not too mushy. The gel memory foam top layer really works. I sink in just enough for pressure relief on my hips and shoulders without feeling stuck. The hybrid springs underneath provide solid support where I need it, Temperature-wise, I think the gel infusion does make a difference; I haven't woken up overheated like on my old pure memory foam mattress. Motion isolation is decent – my partner's thrashing about doesn't typically wake me up. Edge support could be a little firmer for sitting, but for lying down, it's more than sufficient, it's been more than I hoped for for pain reduction and comfort. Strongly suggest if you need that balanced, supportive yet cushioned feel.
