What is the density of the top layer memory foam?

It's memory foam... I am not aware it comes in different densities. It's seems to be the same as our tempurpedic and the memory foam toppers we have purchased for the other beds in the house.

There are two haters of foam in this bed- top is memory foam, bottom is so-called "support foam." 4" of memory foam would be significantly heavier and more expensive.

I'm not sure how to answer your density question because I'm not sure what you mean, but it's a firm to medium firm mattress. If you can find a store that sells Serta, it seemed to us to be the same mattress as the low end foam mattress in the show room. We added a gel foam topper to it, but the foam softens with your body heat and conforms to you as it warms up. We have both been very satisfied with it.

Not really sure what you mean by densities, but each layer is approx. 3" thick.

Have a spring mattress with a foam layer on top --- no problem -- but don't know about memory foam

It is about 2" thick and soft. Might help you giving you some cushion if your mattress is very firm. It is not helping me however. My mattress is begining to sag in the middle, so adding a soft layer on top is not the best idea I have ever had! Good luck!

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.

The top memory foam is 3". Do not know the density in pounds. If you read my review, I said this mattress is firmer than the one at home (which is a difference mattress). I think it's good for the price. Time will tell how it holds up. I kept my shipping invoice, order from Amazon and will definitely call the guarantee into play if it doesn't meet expected performance. Hope this helps some.

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 not sure of the thickness and density of each layer. I not home now, but I will attempt to find out for you around 7PM Eastern time, and I will get back with you at that time. When lying on the mattress it feels very thick though.

wasn't sure so i looked it up i just know its heavier..heres what i got off the internet Density Four lb. density foam weighs four pounds per cubic foot. High-density foam is higher quality than low-density foam because a higher density increases the foam's "memory" or ability to both support and conform. Foam densities under three lbs. are considered low density; any foam over five pounds is high density. Both three and 4-pound memory foam fall within the medium-density range, and it is certainly possible to buy a quality memory foam mattress in either of these densities. Durability One important difference between three lb. and four lb. memory foam is durability. Four lb. memory foam will simply last longer than three pound foam. When it comes to memory foam density, you get what you pay for; four lb. foam costs more, but holds up better over the years.

The foam is dense. I put it under a mattress cover to protect it from liquids and myself from the used mattress. I sleep comfortable with it. It is much better than the egg carton type.

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.

From what I understand about the density it's from 1-5, 5 being the firmest. This mattress is a 4.

Actually, I have been looking for a tri layer, (3) as I understand they are the best....Most memory foam mattresses are two layers, with the top one 2-3 inches of real memory foam, and containing a bottom layer of supportive plain foam.....

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

I do not know the density, but I can tell you that this mattress is NOT firm. The body sinks in the mattress, and turning can be a challenge. I bought this item for my mother, she was uncomfortable to get in and out of the bed, and I had to return the mattress.

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!
