Memory Foam: Three Pounds Vs. Four Pounds

The density of a memory-foam mattress pad can make all the difference in the world when it comes to both cost and comfort. This density, measured in pounds, ranges anywhere from 2.5 lbs. to 8 lbs., with unique advantages to each.

Quality

Generally speaking, lower-quality mattress pads are composed of low-density foam, while more expensive pads are usually made up of foam with a density of at least 5 lbs.

Durability

Mattress pads with a higher density used to be more durable; however, recent advances in the production of memory foam have created low-density toppers that last a long time.

Subtle Differences

While the difference between 3- and 4-lb. memory-foam mattress pads may not be readily apparent, closer examination reveals subtle differences.

3-Pound Foam

Mattress pads that are 3 lbs. tend to feel more like a typical foam pad. They are usually made in China and do not provide the support unique to memory foam.

4-Pound Foam

Memory foam with a density of 4 lbs. provides stable support without feeling stiff. Its unique combination of softness and support are known to create the feeling of "sleeping on a cloud."
