Like the title says. I have a winkbed and this is, I'd say, 3/4ths as good as the two thousand dollar winkbed. I don't expect it to last as long, btu with it costing legitimately one tenth what the winkbed was....if it wore out every other year I'd still save a thousand bucks a decade. That said, if you're heavier (I'm 6ft 4 and 340lbs) you will probably find this to me more on the medium, to maybe even medium soft side. If you have back pain, this won't cut it if your'e in that weight class. Below 300lbs, you should be safe, and below 250, you're golden for this to be and feel like the medium firm it's advertised as. Thats something true of almost any mattress though....if you weigh a ton, you need firm to feel medium, etc. Because our bodies put a lot more force on these. Anwyay, again though, unbeatable price, excellent mattress, and I LOVE that they even included a little letter opener like tool to make sure you open it easily without tearing it....not even winkbed did that!!!

I’ve had the same mattress for around 16 years. During that time, its been filled with Polyfill stuffing, as well as a few mattress toppers, to extend its life. Since my bed frame has the wooden planks under the mattress, the overall feeling is somewhat firm. Once the new memory foam mattress was unpacked, it took around a day and a half to fill out to its normal size, which initially made me worry. When the mattress finally filled out, it was time for the moment of truth. Lying down on a new mattress, which isn’t as firm as my previous one, felt far more soothing and peaceful. With chronic pain, actual sleep feels like a luxury, so resting is sometimes the next best thing. This is literally where the mattress excels. It’s amazingly comfortable to simply sit on, with just the right amount of memory foam to contour you perfectly. My couch has a slightly larger than king sized pull out bed, which is also predominantly made out of memory foam. The only thing that holds it back is how thin the mattress has to be to fold up neatly. After finally getting to experience a memory foam mattress that has a substantial amount of cushioned springs underneath it, it’s easy to see why people love memory foam mattresses. Even though this mattress is technically labeled as a hybrid, its actual memory foam layer is just as thick as my couch’s pull out mattress. The additional rest that I’ve had allows me to feel more refreshed in the morning. Now after DJing late at night, I look forward to laying down in my bed after work instead of sitting on my couch to unwind for awhile. If you don't need a very firm mattress, and soothing comfort is what you’re looking for, then you’ve found it, and that definitely deserves 5 stars.

The media could not be loaded. Threads are loose everywhere. Springs can be felt on the sides so the fabric is very thin. The top layer of “foam” is not attacked to the rest of the bed which will eventually roll up or bunch from sleeping on it. Not firm at all! Will be returning

First, I am shocked at how well this mattress is made, for a bed-in-a-box. The photos in the listing shows a thick, quality mattress. And they are completely accurate, compared to what you actually get. When I unboxed it, and then carefully cut the plastic wrapping, the thing literally sprung out at me - knocked off my glasses. There was no harm done - it just surprised me. Be careful! My son uses this mattress on his bed now. I would say it's about an 8 out of 10 on firmness. I'm at an age where I personally need a firm mattress - I sleep fine on a soft mattress, but my back doesn't like it, the next day. What is unique about this mattress, compared to other mattress-in-a-box options we have tried, is that this one has sturdy springs built into the bottom section of it. So really, what you are getting is a mattress and box spring. I was totally impressed and surprised with that part. Overall, the value you get is incredible for the price. If you don't mind a slightly firmer mattress, this is a great option. I will keep an eye on this brand in the future. My guess is that they will be making noise in the mattress industry.

This mattress feels like it should be twice the price. I'd compare it to a nice not-base-level Se@ly. This one is Medium-Soft and has a lot of nice cushion on the top with supportive springs inside. It comes compressed in a box, and it's pretty heavy. Awesome that you can get it delivered or carry in a small car, but that does mean that there is some distortion in the cover when it had fully expanded. I had to push and pull a bit to get it to sit straight and not look wonky. It hasn't shifted back, though.
