Item Firmness Description: Medium Firm
Item Thickness: 12.0 Inches
Size: California King
I ordered this mattress yesterday and already have it unpacked in my house. The firmness/softness is perfect. It is slightly larger (3 inches) than my old Cali King but that's ok. Also does NOT have a weird smell like most packaged fabric products. Can't wait to sleep on it tonight!

It truly is a cal king in a box. No unpleasant or pleasant odors. We gave it 3 days before we slept on it. It's as advertised. It's comfy. Get 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.
