Which side lies against the bed - the less thick and more firm pale-yellow side or the thicker white foam side?

I put the thin layer up. I think it's memory foam plus that way the zipper is down and away from you.

The "yellow" foam is the primary "mechanical" media, the "grey" is the bio-media. Rinse the yellow but never the grey.

The bed is hard. Not extremely firm, there is some give. I think you can only use one side.

This bed is firm, but has give because it is foam. If you sit on the edge, it will give a bit. The bed forms to your body and supports all over. No you cannot use the bottom side.

This mattress is quilted on both sides, one side is a tack and jump quilting which gives a little softer feel and the other side is a continuous quilt which is a firmer feel. This is how you get the 12 different levels of firmness. Please let me know if you have any other questions. Thank you

I really can't tell the difference from one side to the other. This is a very firm pillow and I like very much. I suggest if you buy the pillow buy the pillow case also.

It's the same on both sides. Naturepedic makes another mattress that has a plush side and a water resistant side, but this one is the same on both...water resistant covering.

I ordered the 3inch one if that answers your question. As for how it wore, I realized that in the winter, when my house was cooler, the foam was a lot ... stiffer? less pliable? than when the weather was warmer. Maybe thats why I developed back problems but I moved onto something else anyway.

I've never actually owned a foam mattress before, so it's hard for me to say, but I would assume it's more like a classic type foam. Sorry I can't be more helpful, maybe someone else can shed more light on it.

I wasn't aware there's a difference in the sides. They both look the same. We're planning on flipping the infant mattress every 6 or so months, at New Year's and the Fourth of July, as we do with our own mattresses.

Density relates to how tightly the foam is per square inch. It actually relates to how much the foam mooshes when you lay on it. The higher the density the more resistance to weight. Think of sitting on a cheap foam pad on a chair. It would flatten easily and you would feel the surface below it quite quickly. A dense foam pad would keep you above the hard board. My understanding the higher the foam density the longer it will provide the cushioned sleep you want. If you and your partner are large people you should be concerned with both depth of the matress as well as density of the foam. However if the density is too great it may not have the "coosh" you would expect. Non scientific answer but the best I can do

Both are firm. Yes the whole bed slides underneath. I ordered feather mattress covers and it makes this bed just perfect.

The foam is very firm. The wedge worked better for me under my memory foam mattress rather than on top of it.

I would say it is the additional foam, the headrest and the longer warranty. I bought this bed because I had a 3" foam bed that only lasted a year and sometimes my lab/shepherd mix likes to lay with her back up against something and sometimes she doesn't and this bed was large enough for her to lie either way. I have definitely seen a difference in her level of stiffness after a night on this bed.

There is a small layer of foam on the bottom, and thick foam on both sides. Well made, works great. Worth the money.

It is the same on both sides. I absolutely love it. Lightweight, so easy to make up the bed.

I have one that has both. I also have one that has memory foam only. I think they are both fine. both are about 4 inches thick, that's important.
