What's the density of each layer?

4 lbs is the density of the foam. Please let us know if you have any more questions.

I'm not sure. I use mine just about every night, and I haven't had any issues with it losing density.

I don't recall the density but I bought it for my little boy and he wanted a really soft bed and this one is exactly that. If you are looking for firm, this is not the one for you. My son loves it though.

I honestly couldn't say what the density is. I've not been able to find any information Regarding foam density of this mattress. However, it is a firm mattress for me, but I'm 6'2" 170 lbs.

I e-mailed asking the same question in early June and Chuck confirmed that they still use 2 lbs density poly foam in the 12/1 bed.As far as I understand each layer is not a different density as density does not directly equate to softness (ILD), but rather quality/durability. At least 1.8 lbs poly is the usual recommendation. http://www.themattressunderground.com/mattresses/support-cores/polyurethane.html

it is pretty dense....it holds up to our weight (250# each). We put it over our matress in our 5th wheel. We sleep so much better. It really is a great product. Better than I thought it would be. The actual thickness is about 4 inches.

Sorry, I checked the tags and didn't see a density rating. It is kind of squishy, but have found it to be very comfortable and worth the price.

Sorry cannot tell you because I am in the middle of a move and everything is packed away. Good Luck

PLA has a density of about 1.25g/cm^3. That means that a 1 kg spool is 800cm^3 of material or a 10cm x 10cm x 8cm box (roughly 4" x 4" x 3 1/8" ). most prints are not solid though so there are a lot of variables that can influence how far filament can go.

I don't understand, because the product description is 8" thick. But it also says, 2" gel foam layer, and 4" high density foam layer. Equals 6"..... Some say their product is 2" thick total (only the gel layer, and others say 6-7 inches assuming a 4" high density foam layer is included.....WHAT COMES WITH THIS ITEM?

It measures exactly 8 inches thick. I would assume that the 5.5 density is for the "give" when you lay down on it and it sinks some. We have this for our 3 year old and am really happy with it. I too have slept on it and and liked it.

I'm not sure how density is measured. ..I would consider the mattress to be firm. ..

1 layer, but as many as you can get on your matt. so either a 12x24 or 12x12 square

I don't really know the per foot cubic density. I just know this is not a quality roller, after using it for less than a month the interior circumference changed by more than 1 1/2 inches. I got my money back and they sent me a complimentary roller which I didn't want, but it arrived with a hole in one end and an uneven exterior surface. I do not recommend this roller and Amazon should not offer it for sale.
