Consumer Guide for a Memory Foam Mattress

Density

• Density is probably the most important consideration when purchasing a memory foam mattress. The density of the mattress is measured by the weight of the mattress, which can range from 2 to 6 pounds per cubic foot, which is the weight of the mattress materials in a 12 x 12-inch tall square. Generally speaking, the higher the density, the better the mattress and the higher the cost.

Materials

• Read the label on the mattress so you are aware of the materials inside. Some lower-priced mattresses might contain allergic ingredients such as formaldehyde. Understand that all memory foam mattress do contain chemical ingredients, and a smell may linger during the first week or so of use.

In-Store Testing

• Visit several stores to test their memory foam mattresses. Wear lightweight clothes such as a T-shirt and cotton pants so that your clothing will be closer to the weight of sleepwear. Begin by testing a 4-lb. mid-range density mattress. Don't be shy. Lie on the mattress in the position you typically sleep in, such as on your side or on your back for at least 15 seconds. Repeat the same process to compare a lower density mattress, such as a 3-lb. and a higher density 5 or 6-lb. mattress. Select a "winning" density, and retest the mattress for at least one minute. Confirm the density choice, but keep shopping. Repeat the same process at two additional stores to compare prices and negotiate the best deal.

Indent Load Deflection

• The Indent Load Deflection (ILD) is actually a technical term used by sales personnel to describe the "springy" quality of the mattress. Do not allow a salesperson to sway you from one model to another based on an ILD rating. The purpose of the memory foam mattress is to have it conform to your body shape and has nothing to do with "springiness." Focus on the density and cost when shopping, not the ILD.

Lifespan and Durability

• Density plays an important role in how long your memory foam mattress will last. As a rule, the higher the density, the longer the mattress will last. You can expect a mattress with a 4-lb. density to last and maintain its shape for three to five years.

Warranty and Return Policy

• Always ask about the warranty and return policy offered. Be aware of what the store requires to authorize a replacement of a mattress or to return the mattress. Find what the warranty covers and for how long. In terms of a return, know what the retailer may or not charge to pick up the mattress along with any restocking fees he may assess, which could reduce the amount of money you are refunded.
