Mattresses are being made with low density foam.....most of them!

Hello,

I’m still searching for a quality mattress. I was looking at the specs for the current line up of Tempurpedic mattresses. They now use a base foam of 1.6 lb polyurethane foam. They used 2.2 lb of polyurethane previously. One of the mattresses that I’m interested in uses a total of 3.5 inches of base foam at 1.6 lb and 5.7 airflow base foam of 1.6 lb polyurethane foam. The memory foam they use on this particular mattress is a good density. However, some others use 3.7 lb memory foam which was bit surprising. How important is that base foam of 1.6 lb polyurethane foam?
Thank you,

Hi Jewels:

I’m not a Tempurpedic dealer, so I don’t have complete detailed specifications of every layer in their lineup. Hopefully someone else here on the forum who carries their products might be able to chime in. I can’t speak to why there has been a change in the new lineup, as I haven’t spoken with any of their designers.

Regarding base foam density importance, the density is still one of the best ways we have to predict foam durability. This also combines with many other factors, some of which are hardness, thickness, area of placement within the mattress, overall mattress layering, use patterns, care, etc. Generally speaking, the higher the density, the more durable the flexible polyurethane foam.

Hopefully the forum moderator can touch base with one of the manufacturing experts here who would have had the opportunity to discuss the new specifications in detail with one of the TSI engineers, and they can share some more specific and accurate information to answer your question.

Hello,

I do know the specs for every Tempurpedic. The base polyurethane foam is 1.6 lb density. Depending on the mattress that can be 6 inches of 1,6 lb foam. So, in general, if a foam mattress has a 7 inch base of 1.6 lb density polyurethane foam, is that make it at risk for issues, or is that good? I’m not sure if that’s good or a weak link.

Thank you,

Hey Jewels,

Thanks for your reply :slight_smile: .

Thanks to expert trusted member @JeffScheuer/ Mattress To Go for his thoughts on your questions. Jewels, he makes an excellent point: “Regarding base foam density importance, the density is still one of the best ways we have to predict foam durability. This also combines with many other factors, some of which are hardness, thickness, area of placement within the mattress, overall mattress layering, use patterns, care, etc. Generally speaking, the higher the density, the more durable the flexible polyurethane foam.”

Polyurethane foam, also known as polyfoam, is one of five basic types of mattress cores within the mattress support layer. It is available in three different grades: a regular grade (the lowest grade of polyfoam weighing less than 1.5 lbs per cubic foot); High Density/ HD polyfoam (weighing between 1.5 lbs- mid 2 lb range per cubic foot); and High Resiliency/ HR polyfoam (weighing 2.5 Lbs+ per cubic foot). For those following your research, Phoenix’s articles “Mattress Support Cores: Overview” and “Mattress Support Cores: Polyurethane” explore this common foam’s applications in more detail. Question: which Tempurpedic mattress are you specifically interested in and as you say you know, what are all of the specs for that model? I don’t find in any of your previous posts any details of your personal statistics/ preferences or other information that might help further explore your mattress durability concerns, those would be a good starting point.

In keeping with Jeff’s thoughts on other manufacturers who may have knowledge of TSI new product specs, I am moving your post to the General Mattress forumfor a wider audience view.

Looking forward to your updates, Jewels :wink: .

Thanks,

Hello,

Thank you for your response. I continue to be concerned regarding the base of the Tempurpedic mattresses. The base foam used to be 2.2 lb in density (polyurethane foam) and now they went down to 1.6 lb in density. I guess time will tell if lowering the density in the base foam will affect its longevity. The upper layers of memory foam are still good in most of the mattresses. I seem to be on an endless journey.

Thank you,

Jewels

Sorry to resurrect this thread, but every current tempurpedic mode is using only 1.6lb poly foam??? Or just certain models? Do you mind posting the specs of each? Also are there any specs on the current hybrid support cores and how those may compare to the current foam support cores?

Hello!

I’m sorry that I’ve missed some posts. Thank you to all who have replied. All of the current Tempurpedic mattresses use a base foam of 1.6 lbs polyurethane foam. I was able to find a site that posts the specs for every Tempurpedic mattress that they sell. It matches exactly to what other stores have listed as the density of each layer of foam. They do use some high density memory foam on most of their mattresses. There are a few exceptions.

I’m still interested in an Aireloom mattress, but have read many complaints on Yelp regarding durability. It’s an expensive mattress and I though it’s nice, I can’t afford to have it fail at the 6 month or more mark. I wish someone here knew more about Aireloom.

Thank You Everyone,
