I don't have the density but I can tell you this mattress is slightly firmer than the Tempur models. Very good to sleep on though.

Don't know the actual density, but didn't compress much when slept on. Was nice but not as thick as I thought it should be for the price. Hope this helps!

It is 3 pound density. The weight of king size is 21 pounds. Here's more info: Foam is mite and allergen proof 10 year limited warranty 3-pound foam density Memory foam is made in the USA Twin Dimensions: 75 x 39 x 2 inches Full Dimensions: 75 x 54 x 2 inches Queen Dimensions: 80 x 60 x 2 inches King Dimensions: 80 x 76 x 2 inches California King Dimensions: 84 x 72 x 2 inches

The unit itself is not heavy . To me it feels about 3-pounds but I have it on a hook stand designed for it by the manufacturer so the motor part is never handled. Shipping now a days is a different story. We have large sections of foam weighing only 7-pounds that fits inside a box made for a case weighing 40-ponds but the shipping cost of the 7-pound foam is based on the cost of the box size and is the same cost as the shipping cost for the 40-pound case even though only a 7-pound piece of foam is in side. The entire shipping industry is this way now. I hope I helped you with this. Now a days when you order something, don't look at the total weight. It will always throw you for a loop. If weight is important, only look at the actual weight of the item itself. Contact the person / company and ask for the weight of the item itself if that information is not given in the description.

I am not sure of density of it, all I know it is pretty supportive and firm, but not hard. It is very comfortable.

Super comfy yet medium firm. We have it on top of our futon mattress and way more comfortable with it. Don't know the density. We are super happy with it.

This is 3" thick, and I thought of medium support. It went on top of a very firm mattress and made it feel like a nice memory foam mattress. I have two Tempurpedic beds. This was for my daughter's apartment. Made an uncomfortable bed feel awesome. So, I would say medium-soft density.

Honestly the density is like one of those large sponges you use to wash your car. I don't know if that sounds good to you but it is really very comfortable. It is dense enough that even someone in the 180 lb range would not feel the mattress underneath it. I think it adds a great level of cushy comfort to an existing mattress.

None of these answers tell the weight density of the memory foam; is three or four pounds?

wouldn't LxWxH (in inches) be 80x60x1.5/1728 = cubic feet of foam for the product? this does equal 4, (or 4.166666) - if it's 4lbs per cubic foot as you suggest, 4 (lbs density) x 4.16666 (cubic feet of foam) this would suggest a product weighing 16.6666 lbs. if you check the shipping weight it's only 14.8lbs, product weight is stated at even less yet 12.5lbs. 12.5 lbs product weight, divided by cubic feet of foam product, or 4, equals 3lbs density. it used to be that fxi (foamex) brands were associated with density, aerus was 4lb, sensus was 5lb density etc. if you look at the foamex website, it states the new aerus natural line comes in 3, 4, 5, 6 and 8lb densities. so it's very possible that this is in fact legitimate aerus memory foam at a 3lb density which would explain its' lower price than usually found for 4lb memory foams with the aerus name.

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.

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.

As you've pointed out, density = mass / volume. So yes, you're correct in thinking it should be about 41 "pounds" (18.5 kg, since we're talking "mass"). I didn't actually weigh mine, and I don't recall what the shipping label stated it weighed, but I wouldn't be surprised if it's about that.

The packaging does not indicate a density weight, however it is comparable in my opinion to the Sleep Joy 2 inch 3 lb density topper I purchased for my daughter's bed. Hope that helps!

Mr. Gruber if your weight exceeds 175 lbs. that 2-lb. density foam will break down quickly. It's a shame the company doesn't maintain a website for legitimate questions that Buyers have. Best to your search. Please see Atul Shukla's statement below me.

The manufacturers website lists it as 5lb density with 20 ILD for the memory foam comfort layer, the support layer is listed at 1.8lb density with 36 ILD.

I know this was asked a while ago, but I emailed the seller after I received the mattress (which, I have only been sleeping on for two days but am very happy with so far). They emailed back that the 7-inch base layer of high-density foam is a 4lb density... not sure about the others, but the base layer is most important when determining the overall durability, comfort, etc. I consider 4lb to be perfect for me, as that is on the medium-firm side.
