Memory Foam, Mattress and Topper Pad Buying Guides Updated

The most popular pages of our website are our Memory Foam Buyer’s Guide, Memory Foam Mattress Buying Guide and Checklist, and the Memory Foam Topper Pad Buying Guide and Checklist where I share the insider’s tips I’ve gathered from my 20+ years selling memory foam. I recently updated all these and added new content, which I hope will give you the information you need to find the right memory foam mattress or topper for you at the right price.


What is the difference in memory foam density?

Memory foam’s density is expressed by the weight of a cubic foot of that particular material. So, for example, the memory foam we use for our topper pad has a 4 lb/cubic foot density (or more generally referred to as 4 lb memory foam). This simply means that a cube that is a foot in each dimension made of this particular foam would weight 4 lbs.

What is a Memory Foam Mattress?

Over the years, mattresses using memory foam have become known as “memory foam mattresses”. But I’ve found that there is a lot of confusion over what exactly this means.

What this doesn’t mean, to many people’s surprise, is that the mattress is made completely or even mainly of memory foam.

Instead, memory foam mattresses typically have a basic “core” of standard polyurethane foam (often 5 – 6″ thick) that serves as the support layers of the mattress. And then on top of this is put layers of memory foam (from 2″ to 4+”, depending on the feel the mattress manufacturer is going for).

What Do Density and ILD/IFD Ratings For Memory Foam Mean?

We often get asked about the density of the memory foams we use in our memory foam mattress and memory foam topper pads, and once in awhile about their IFD/ILD rating.

And while we are happy to provide this technical data, I want to be clear that these technical specs alone do not give you a real indication of the comfort of a particular memory foam mattress or topper.

Why I Still Like Pure Memory Foam Vs Gel Foam

I get a fair amount of questions about gel foam — what is gel foam, why I’ve only carried memory foam beds (for more information on buying a memory foam bed, click here to see our in-depth memory foam mattress buying guide and checklist) and never carried a gel foam bed, and whether gel foam “better” than memory foam?

Just Posted 4 New FAQs On Memory Foam

I got busy over the weekend and started writing up some of the FAQs that we have heard over the years from our customers about memory foam. I got 4 done to start with, with more on the way soon. The first 4 were – and you can click on the links below to take you to the FAQs :

Memory Foam Mattresses: Keep it Breathable

Memory foam mattresses need to allow air to circulate. This helps prevent mold. Some companies, including “leading brand,” sometimes fail to explain this and I talk to many sad people who lift up their mattress and find it covered with mold because no one told them they shouldn’t sit their memory foam mattress on solid wood. Here’s the lowdown on keeping any memory foam mattress mold-free:

A Memory Foam Topper for Your Dorm Room Mattress

Every year around this time, we get inquiries from parents and grandparents looking for memory foam toppers for students going off to college in the fall, usually for the first time. (Funny how it is rarely the student we hear from, but we do know who is usually paying the bills, don’t we?)  Sometimes the colleges even recommend bring a memory foam topper to school when the student arrives.  Despite what the colleges may recommend, we do not recommend this. Here’s why…

Why a Memory Foam Topper Can’t Fix a Worn Out Mattress

Occasionally, we talk to people who are looking for a memory foam topper to “fix” their old, worn-out mattress. Unfortunately, a memory foam topper isn’t a magic wand that can fix a mattress that is past its useful life. A mattress that is worn-out and has dips, sags, or lumps should be replaced. So what is a memory foam topper for then?

Memory Foam Mattress Firmness is in the “Eye of the Beholder”

There is a saying that “beauty is in the eye of the beholder.” That is true not just for beauty, but when is comes to memory foam mattress firmness, or any mattress’ firmness for that matter.  What that means is that what one person thinks is a mattress that is too firm, another may think is too soft.

Don’t Fall for High Pressure from Memory Foam Mattress Sales People

Unfortunately, shopping for a mattress is one of the worse shopping experiences a person can have. That’s too bad, because it doesn’t really have to be that way.  Shopping in a retail mattress store, the ones you see in the shopping centers yelling “SALE!” all the time, can be a dreadful experience.  Ads are constantly running on TV, in print, and in front of the stores.  Can there really be a “sale” all the time?  (That’s a whole other issue…)

Is That Really a King Size Memory Foam Mattress?

Every now and then, we get a call from someone who thinks they have been sent the wrong size memory foam mattress because they lay it out on the foundation (still in the plastic) and it is too short and too narrow to be the size they ordered. I assure the customer to open it up and they will find that it does come back to size very quickly.  In fact, our memory foam mattress is at 90% of its full size and ready to use in just one hour.  You can put your mattress protector and sheets on it and use it at that time.  It will take an additional 24 – 48 hours for the mattress to be at 100%, but it will not harm the mattress (and you won’t know the difference) one hour after opening it.
