Amerisleep vs. Memory Foam

When it comes to memory foam, no one brand can claim to have the only "true" product. Though each producer might have their own recipe, everyone creates memory foam using the same NASA-inspired technology. When comparing Amerisleep to memory foam, it is important to look at measurable factors like:

Characteristics of memory foam material

Here are key features of Amerisleep and generic memory foam.

Amerisleep Bio-Pur Memory Foam

Amerisleep Bio-Pur™ Memory Foam:

  • Dissipates heat 10x faster for cooler sleep
  • Allergy-free with no off gassing
  • Uplifting and outstanding support for better spine alignment
  • Recovers faster than traditional memory foam, allowing for instant contouring
Other Memory Foam

Generic Memory Foam:

  • Compresses through low response to body temperature or pressure
  • Synthetic, petroleum-based product producing strong chemical odor
  • Bottoms out under weight; loses spinal support
  • Lesser quality materials wear down faster over time

comparing types of memory foam

While the processes and ideas behind most memory foams prove similar, key differences can be found in the materials, quality, and pricing among brands.


Density describes the weight of one cubic foot of memory foam material. Higher density foam (over 4.0lbs) provides better support by contouring tightly to the sleeper for even weight distribution and pressure relief. Lower density foams (under 4.0lbs) have more loosely spaced cell structures that do not exhibit the pronounced "floating feel" of dense foams, and thus can be prone to "bottoming out" while not effectively relieving pressure points. Denser memory foams can also hold their shape and rebound longer than low density materials.

The mattress core, the base layer that lies below the actual memory foam, also plays a significant role in quality. This is what provides the support component of the mattress, and should not be overlooked when comparing beds. Cores are also made of polyurethane-type foam, though the density requirements differ from memory foam. A good-quality mattress core should have a density around 2.0lbs in order to deliver comfort and durability.

Memory Foam Density
  • Generic memory foams tends to range in density between 2.0 and 4.0lbs. Cores can be 1.5lb density or lower.
  • Amerisleep's density in the majority of mattresses is 4.5lbs, with the Colonial model also incorporating 5.3lb density material. Mattress cores are composed of high-quality Bio-Core™ foam with a 2.0lb density.

Heat dispersion

Memory foam is often associated with trapping heat, but materials can vary in this regard as well.

  • Traditional closed-cell memory foam mattresses can impede breathability and contribute to heat buildup for those who naturally get hot at night.
  • Amerisleep uses an extreme open-celled foam that proves highly breathable and effective at dispersing heat.
Cool Memory Foam

Response & recovery

A key trait of all memory foam is the ability to conform to sleepers and rebound once weight is removed. How memory foam responds and quickly recovers can vary amongst brands.

  • Memory foam usually softens slowly via the sleeper's body heat, and thus also rebounds slowly, once it returns to room temperature.
  • Amerisleep's material responds to pressure, allowing for instant contouring and quick recovery independent of room temperature.
Memory Foam Response Time


One of the most notable and obvious differences between retail store brands and other memory foam products is price. In some cases, quality memory foam mattresses that are comparable to most leading national brands can be purchased at deep discounts — even at half the price! However brands that are extremely cheap, like those sold at large discount retail stores, may present a compromise of quality for savings.

Average Cost of Memory Foam

Amerisleep vs. memory foam: what's really important?

When comparing Amerisleep's Bio-Pur™ memory foam with other memory foams, aspects like technology and general properties will prove similar. Ultimately, the key factors that consumers should consider are the materials used in manufacturing, response time, heat dispersion, and the cost relative to the benefits offered. Keeping these four factors in mind when considering a new mattress will make the decision an easier and safer choice.
