What is the density of the memory foam layers?
216131
Thanks for your question! This mattress is made from 3 layers of High Density memory foam. There is a 5 inch layer of high density therapeutic foam, a 2.5 inch support layer of high density memory foam and the top layer is a 2.5 inch layer of gel infused memory foam. Unfortunately I don't have the exact density of each layer but 'high density' would mean 6 pounds per cubic foot or higher. I hope this helps!

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

Therapeutic Support Base: 2lb Ventilated Cool Airflow Layer: 2lb Memory Foam Comfort Layer: 4lbs I emailed them and got this information. It should be reliable :)

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

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 went and checked...it really is memory foam. I does not seem as dense as what is on my bed but it has made a world of difference in my husband's sleep apnea and acid reflux.

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.

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

I never did find out the density. But when the item arrived, the item was not the correct width. It was ALMOST as wide as they said, at one end and the other end was a couple inches shy of the right width. I sent the foam back for refund.

I believe that the 5.5 is the density..... 5.5 pounds per sq. inch, tho' I'm not sure about that. Whatever, it is a fairly firm memory foam, tho' very comfortable to sleep on. I have no problems with my back or hips hurting anymore from pressure points. My only dislike is that I bought the 4" thick topper, and I find that it shifts on the bed, even with a mattress cover to hold it in place. Other than that, I have no complaints. It's a terrific buy!

Compared to other memory foam mattresses I've tried, this mattress is firm. After a few minutes, you've sunk in about 1-2 inches.

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.

If you read the description it says 2" memory foam layer for soft comfort and a 1" base foam layer for added support.

According to a chart on this website, http://www.sleeplikethedead.com/memory-foam-toppers.html, it's density is estimated @ 3.5lbs but there is no differentiation for 2, 3 or 4 inch thicknesses.

I couldn't tell you exactly, but the top layer of foam is fairly soft and conforming while the bottom layer gives more support and is much denser.If your concern is about any dents being formed, my girlfriend and I are very... rough on beds, so much that we've managed to destroy 3 $1,000+ dollar beds in a matter of a few years, but this one has held up for the last 6 months or so without even begging to sag or lose any of it's original "springiness"

I've tried this out on a hard floor; it's definitely not an adequate mattress by itself. I think 8 inches is about the minimum thickness for a memory foam mattress. IMO, the minimum density for a stand-alone mattress should be 5lb/cu.ft. I think this product is 3lb/cu.ft. The lower density means a shorter life-span and a softer feel. IMO, the perfect memory foam bed consists of an 8 inch thick 5lb/cu.ft. density base with a 3 inch thick 3lb/cu.ft. top. If I may recommend a topper... http://www.amazon.com/gp/product/B000A8BUB0 Good luck!
