Firm and comfortable not deep and soft.

This mat is just right for floor exercises. I need a surface that is flat and yet yielding and this is perfect.  It is only 5/8" thick but gives me relief from the rock hard floor.  Much better than a 2" foam mattress or other soft mat. This keeps the back firmly in line while making it more comfortable.

I am not saying that no one will find this comfortable, but to me it is extemely firm for my personal taste. Good product however, no complaint about smell or anything like that I just find it is not suited to my comfort. But other people may absolutely love it as it is very well made as far as I can tell and I have had it for quite some time.

Very nice mattress.  It is a bit firmer than I am used to but I am not sleeping in a 'hole' with this mattress. It is very comfortable but if you want that 'sunk in' feeling, get a cushier one.

Very firm and keeps your head in upright position. If you like a soft pillow, this is not the pillow for you. No stiff neck here!

I received this product free in exchange for an honest review.

The pillow description states that it is for the stomach sleeper and of firm density.  I am NOT a stomach sleeper but I prefer a firm pillow as I do not like a bunch of fluff about my face as I sleep on my side and feel claustrophobic if my face sinks in too much.

I expected a pillow firmer than the one I received.  Its not too soft, but its not as firm as I would have liked.  Even though it isn't as firm as Id like,  it seems it is working marvelously for me as I haven't had any neck pain and have been sleeping on it quite well.

The price for this pillow seems quite reasonable when I compare it to the other pillows I have purchased in the past.  My family cannot seem to find a pillow we like and stick with it.  So I am both happy and surprised that I have this one and have been using it for well over a month and still enjoy it.

I think I am going to try their full body pillow next as I sleep with a pillow between my knees and in my arms.  I know I will like it as much as this one, it will be money well spent.

I like this mattress because it feels great if I lie on my back. This mattress is REALLY firm though. And the 8" felt more like a 4".

Nice compromise between soft and firm. Putting it on a hard mattress made it much more comfortable but did not feel like you were sinking in. Foam smell went away quickly, no other issues thus far. Great investment for an uncomfortable bed.

They take little space to store when not in use. They feel firm and are comfortable.

This is a comfortable pillow. It is extra firm, but at the same time, it is also soft. I sleep on my side, and this pillow gives me support while still feeling comfy like a pillow. It is not a pillow that you sink into. This pillow is fluffy and hypoallergenic. It smells fresh and nice. This is a stand-alone pillow. You don't need to use a second pillow with this one, because it is firm enough and very fluffy.

The product dimensions listed for it are not accurate. This pillow is supposed to be standard size, but I have another standard size pillow that is longer than this one. I also think this pillow might be just a little too firm for me. But if you need an extra firm pillow, this is the one to get.

My wife and my back are starting to hurt after one year. I can't say I'm very happy with this purchase.

Reviews claim this is a soft bed. I'm afraid that's not very accurate.

Previously, we were sleeping on a coil double pillowtop extra plush bed. This bed is probably what I'd call "medium" firmness.

It was well packaged, easy enough to setup, and feels well constructed. There was no gas smell.

After unpacking it, I left this mattress on the floor for it to regain its proper shape after being rolled-up for shipment. After 3 days, as the instructions say, I laid on it while it was still on the floor. It was quite firm, I was not in any risk of sinking onto the floor. I had gotten this company's memory foam mattress topper and love it, it was soft and very comfortable so I was expecting this mattress to also be soft. It's probably good for my back for the mattress to be 'firm.' Then I put it onto the bed frame which is a metal mesh, not wooden slats, and laid on it again. It was softer. Maybe it will hold up well. Oh it has a fabric cover that zips off, so you don't need a separate mattress cover.

Alright, this mattress is firm and if firm is what you like then this is it. Its comfy and once this things molds to your body you won't want to move. If you are reading any of the other comments they'll say that the corners don't fully inflate. They are correct. They don't. They'll be 9 inches after 24 hrs. Do i sleep on a tiny corner? No. I didn't care. Still don't. So after 6 hrs this thing will be fully inflated. It goes pretty fast. After 10 minutes of it being out of the plastic it was noticeably bigger. The packaging it comes on is really snug. I ripped the bag it came with to get to the plastic inside and the box is pretty heavy and I recommend getting another person to help you bring it inside.
The picture I posted is after 2 hours of it being out of the box.
1 month- I have had zero back pain since I got this mattress. I sleep more soundly and wake up in a better mood. Since my sleep isn't being interrupted by discomfort I started dreaming again too.

This mattress is like sleeping on a spongy rock (a good thing in my opinion). It's very firm but comfortable and I like that it doesn't have the sinking in sensation that comes with memory foam. Pretty affordable compared to other foam mattress options too.

Not very supportive, but it is comfortable.

After reading many reviews my husband and I decided on this mattress. He has a bad back and likes a firm mattress. I like a firmer mattress as well but don't want to feel like I'm sleeping on concrete. This mattress was firm while still very comfortable. Off gassing was not bad at all. We have a 18 month old who sometimes comes in bed with us if he's sick or scared and I was concerned about that but it hasn't been an issue.
