What is density? How about firmness? Is there a difference?
Yes, there certainly is a difference between density and firmness! They are two unique characteristics, and while they both play a big role in foam, they don't actually have a bearing on one another.
To start with, density is nothing more than the weight of a 12" x 12" x 12" block of a particular style of foam. The weight of that block is that foam's density. The heavier the foam, the more physical performance material exists in the foam, versus open air space. This means heavier, higher-density foam is more durable and has greater longevity than lighter, lower-density foam.
Firmness (Indentation Load Deflection, or ILD), meanwhile, is a measure of the force it takes a 50-square-inch circular plate to compress a foam sample no smaller than 24" x 24" x 4" by 25 percent. The pressure in pounds it takes to achieve that compression is represented as the material's ILD. As you would expect, a higher number means it takes more weight to compress the material, so that material is firmer. Lower numbers mean a material is softer.

Should I use a cover on my foam mattress?
Yes! Using a cover will extend the life of your bedding by reducing wear and tear, and by reducing the chances of an accident causing damage. Like a traditional mattress, foam isn't easily cleaned, and the material's absorbency makes that an even bigger issue. Using a cover also means you can keep your bedding fresher by having something over it that's much easier to launder.
Memory Foam Questions
What is memory foam?
Originally designed by NASA to help provide relief from the G-Forces of takeoff, the material has revolutionized the comfort and support industry. Formulated with visco-elastic polymers, memory foam will soften from body heat and yield to pressure, then slowly return to shape. This provides fantastic pressure relief and helps boost and maintain circulation.
Is memory foam the same as latex foam?
No, while both are open-celled foam materials that possess fantastic pressure-relief characteristics, memory foam and latex foam are two different materials.
What density should I get?
3LB White: Suggested for those who want the contouring of memory foam at an economical price-point.
4LB Blue: Suggested for those who want higher-quality memory foam at a great price.
5LB Pink: Suggested for those who want top-quality memory foam at a competitive price.
What thickness topper should I get?
2" Thickness: Most typically suggested for stomach-sleepers, or those who just want a little bit of softness from a cost-effective memory foam pad. Any thicker than this, and stomach sleepers tend to experience back problems, as their torso will sink too deeply and cause pressure and flexing. Good for lighter individuals as well.
3" Thickness: The most typically suggested thickness, it works well for side, back, or combination sleepers, stomach-sleepers aside. This is the thickness most leading brands use in their layered memory mattresses. A 3" memory pad will provide a solid balance of molding and support capabilities.
4" Thickness: Suggested for any combination of sleeping position, except for stomach-sleepers, again. Heavier individuals may also want to go with this thicker option, to prevent bottoming out. 4" will feel softer as you have more material to sink into and will receive even more pressure relief than the 2" or 3" pad.
Latex Foam Questions
Is latex foam the same as memory foam?
No, while both open-celled foam materials that possess fantastic pressure-relief characteristics, latex foam and memory foam are two different materials.
Is the latex foam you sell natural or synthetic?
The Dunlop latex foam we carry is 100 percent all-natural latex foam.
