How Heavy is A Memory Foam Mattress?

How Heavy is A Memory Foam Mattress?

While memory foam mattresses have been around for many years, there are still a lot of questions around them. Specifically, a lot of prospective buyers wonder how heavy is a memory foam mattress? The answer depends on a variety of things such as the size of the mattress and the density of the foam that is used.

Memory Foam Density

Memory foam comes in a variety of density options, with low density being the lightest weight foam available. Medium and higher density foams add weight and bulk to the mattress. The term density refers to the overall number of cells that are found throughout the mattress. A dense mattress is considered to be made up of any memory foam that is over 4.0 lb, while medium and lower density mattresses are found below that threshold.

Mattress Size and Weight

The majority of memory foam mattresses are shipped to your door in a compressed state, meaning they have had most of the air removed from the mattress to compress the cells to create a smaller package. However, this doesn't remove the weight just because the package is more compact! Fortunately, even a king sized mattress is still light enough for a normal individual to carry inside by themselves. However, if you're heading up several flights of stairs, around corners or have challenges with lifting and carrying, it's probably best to ask a friend or family member for some assistance. Twin mattresses contain much less material than a king-sized mattress, so the weight is accordingly less.

Memory Foam Mattress Weight Estimates

Overall there's a wide range of weights ranging from 30 to more than 150 lbs. dependent upon the model & size you choose. Here's a good rule of thumb by mattress size:
Memory Foam Mattress Size Estimated Weight
Twin 40-60 lbs.
Full 55-80 lbs.
Queen 80-100 lbs.
King 100-150 lbs.

Are Memory Foam Mattresses Heavier Than Other Mattresses?

If you're wondering how a memory foam mattress compares to other mattress constructions, SleepLikeTheDead shows they are very consistent with innerspring & hybrid mattresses, heavier than futon, air, & regular foam mattresses, and lighter than latex mattresses & water beds. Although memory foam mattresses are heavier than some options, they are still nearly 50 lbs lighter than a latex mattress, and most people should have no trouble moving them as needed within the home.
