I purchased the Zinus 8 Inch Gel-Infused Green Tea Memory Foam Mattress / Cooling Gel Foam / Pressure Relieving / CertiPUR-US Certified / Bed-in-a-Box, Queen size. It has three different layers of foam and is not a hybrid model. First is the 4.5" high-density base support foam, next is the 1.5" comfort foam, and on top is the 2" gel-infused memory foam. This is the first foam mattress I've ever owned, and I'll never go back to using the old box spring mattresses I've had all my life. The first night I slept on it with only a single sheet covering over the mattress and I was stunned by how nice and comfortable it feels compared to everything I've ever slept on before. The second day I installed the SafeRest Queen Size Premium Hypoallergenic Waterproof Mattress Protector, which is quite thin as it's a mattress protector and not a mattress "pad." I noticed no difference in how it feels in any way with this addition after using the bed all day and sleeping for 8 hours the second night. I believe it's so comfortable because of how your body sinks down into the foam slightly which supports your mass more uniformly than other surfaces can. Don't get me wrong about this, it's still a quite firm mattress so it's not like you sink way down into it. I wish there was some way I could better express just how much I love my new Zinus mattress!!! This is like sleeping on a cloud!
I've read some negative reviews about people who've removed the cover that comes on the mattress to wash it or for whatever reason and then went nuts complaining about loose fiberglass fragments they encountered afterward. I believe the tiny amount of fiberglass material built into the cover is part of the fire-retardant material that makes up the cover. I also believe the warning the manufacturer gives about not removing the cover is their way of being over-cautious about the possibility of customers coming into contact with fiberglass fibers if they do so, and anyone who has removed the cover has NO ONE TO BLAME BUT THEMSELVES for any problems they encounter for failing to follow the manufacturers instructions. I haven't removed the cover on mine but I did open the zipper about 12" so that I could stick my bare forearm inside and rub it around to see for myself if there really was loose fiberglass fiber but I didn't notice any indication of this at all. My recommendation if you ever feel the need to remove the cover to wash it or whatever is remove the cover, deflate the air out of it and then CLOSE the zipper (without turning it inside out) and then arrange it around the center post of your washing machine. This will ensure the inside and outside of the cover won't come into contact with each other. Wash on a delicate setting, no bleach, then after removing it from the washing machine don't put it in the dryer, just lay it out on the floor to dry before putting it back on.
The first picture was taken just 5 minutes after removing the mattress from the box and it's a full 7". 36 hours later it had expanded to the full 8" as can be seen in the second picture. After about 36 hours it was fully expanded and was very smooth and flat with square edges, and it looks almost perfect in every way. I have no idea how long this mattress might last, but after paying only $200 plus $18 in sales tax with free shipping it's easy and cheap enough to replace. I'm still using my old bottom box frame but since the distance between the support slats is a full 6" on my old base, I show in the third picture how I installed (with a few screws) some pieces of 1/4" plywood to the top of it for better support for the foam mattress. I simply bought and installed 3 pieces of 1/4" plywood at 24" x 48". I needed to cut the width of one piece for the foot end of the bed down 4" so that the plywood would break over the supports slat of the old box base. If you choose to follow my example you may need to modify this to some extent depending on the spacing of the support slats of your base.
