How Much Does A Memory Foam Mattress Weigh?

Memory foam mattresses vary widely in weight, depending on several factors such as size, thickness, density of the foam, and additional layers or materials included in the mattress construction. A twin-size memory foam mattress might weigh between 25 to 50 pounds (11 to 23 kg) while a queen-size can weigh from 40 to 100 pounds (18 to 45 kg). A king-size memory foam mattress can weigh anywhere between 50 to 150 pounds (23 to 68 kg). These figures are estimates and can vary from one brand to another.

The Influence of Mattress Size on Weight

When considering the weight of a memory foam mattress, the most significant factor is typically the size of the mattress. Naturally, the larger the mattress, the more material it contains, and therefore, the heavier it will be.

Twin Size

Starting with twin mattresses, which are commonly the smallest size available for adults, weights can range significantly. These are popular in children’s rooms or for single adults with limited space.

Full Size

Moving up in size, full mattresses provide a bit more space than twin mattresses and, accordingly, weigh more. These are suitable for single adults who want more room or for guest beds.

Queen Size

Queen mattresses are among the most popular sizes for couples, as they provide a good balance of space and affordability. As they offer more surface area than twin or full mattresses, the weight increases correspondingly.

King and California King Size

King and California king mattresses provide ample space for couples and are the largest standard sizes. With their extensive dimensions come the highest weights in the category of memory foam mattresses.

The Role of Thickness and Density

While the size of the mattress has an obvious impact on weight, thickness and density also contribute significantly.

Thickness of the Layers

The overall thickness of a memory foam mattress can range from 6 inches (15 cm) to 14 inches (35 cm) or more. Thicker mattresses contain more material, which naturally results in a heavier mattress. Mattresses with additional layers, like a high-density foam base or a gel-infused memory foam top layer, will weigh more as well.

Foam Density

Foam density is measured in pounds per cubic foot (PCF) and affects mattress weight as well. Memory foam densities typically range from 2.5 to 5.0 PCF. High-density foams are denser and more supportive, but also heavier. Low-density foams are lighter and may not provide the same level of support or durability as higher-density foams.

Additional Components and Materials

A memory foam mattress usually has more components than just the memory foam itself. These materials all add to the overall weight.

Cover Materials

The cover fabric, usually made from cotton, polyester, or a blend, isn’t particularly heavy in itself, but covers that include additional padding or quilting can contribute to the overall weight of the mattress.

Support Cores and Transition Layers

Many memory foam mattresses also feature a support core made from high-density polyfoam, and this layer is often the heaviest part of the mattress. Some mattresses also include a transition layer, which serves as a buffer between the soft memory foam and the firm support core. This may also increase the mattress weight.

Cooling Layers

Memory foam mattresses with cooling features, such as gel-infused foam, copper, or graphite infusions, may weigh slightly more than traditional memory foam due to these additional materials.

Transportation and Setup Considerations

The weight of a memory foam mattress not only affects the delivery but also the setup and the ability to move it around.


Most memory foam mattresses are delivered in compressed, rolled packaging to make the shipment easier. However, once the mattress is unpacked and expanded, maneuvering it can be challenging due to its weight and flexible nature.

Handling and Setup

Setting up a memory foam mattress should ideally be a two-person job, especially for sizes queen and up. It’s important to consider this if planning to move the mattress to another room or house.

Maintenance and Longevity

Heavier memory foam mattresses are often associated with better durability and longevity, but they also require more effort when it comes to maintenance such as rotating or flipping (if recommended by the manufacturer).

Finishing Thoughts

In summary, the weight of a memory foam mattress varies widely and is influenced by many factors, such as size, thickness, density, and additional materials. When choosing a memory foam mattress, it’s important to consider the implications of its weight on delivery, setup, and maintenance. No matter which size or type of memory foam mattress you choose, understanding these factors will help ensure that you are prepared for handling and caring for your new sleeping surface, ensuring a restful night’s sleep for years to come.
