The low density foam mattress we offer is a six inch thick slab of foam with medium firmness. The mattress comes standard with a removable cover.

This trundle bed size mattress is 73 inches long and 6 inches thick, slightly shorter than the standard 75 inch length mattress. This mattress is designed for use with our trundle bed. The trundle bed is a low bed that fits underneath most beds and can easily be pulled out for sleepovers or extra storage space. The trundle bed is boxy and perfect for storing an additional mattress. The mattress is designed to fit inside your storage trundle nicely.

Usually, the length and width of mattresses are standard but the thickness does vary.

This foam mattress is medium firm. Mattress firmness refers to how soft or hard a mattress feels when you first lie on it. It is usually determined by the type of material and design of the mattress. The firmness of a mattress is rather subjective and a matter of personal choice.When we say a mattress is medium firmness, it is in comparison to other types of foam that are softer or firmer.

Usability of Foam Mattress

We recommend foam over coil mattresses for use on bunk and loft beds. Since clearance is essential on a loft or a bunk bed, you need to use a low profile, i.e. thinner, mattress. Foam mattresses are usually more comfortable than coil mattresses of lower thickness. Also, there is a weight limit for bunk and loft beds. Foam mattresses are often much lighter than their coil counterparts.

The mattress is composed of low density foam and is not very durable. It is suitable for use in either guest rooms or spare rooms. The mattress is ideal for both kids and lightweight adults.

Low Density Foam in General

This mattress is made of Polyurethane, a material similar to a kitchen sponge. Low density refers to weight to volume ratio. Like fluffy bread, the low density foam has more air pockets between its molecules. This is why it breaks down faster over time if you compare it to high density foam.

Removable Cover

The cover of this mattress is removable. This means you can wash it and put it back on if needed. The three-way zipper on this cover makes the process of removing it much easier. The cover is made from 100 percent polyester, which makes it durable and long-lasting.

It is worth mentioning that this cover is not going to act as bedding. You do need to buy fitted sheets for your mattress.


We ship this item as one unit, so you do not need to do anything. We even put the cover on for you before we ship the mattress.


We sometimes vacuum pack this mattress before we ship it out. In this case, you will receive a smaller version of the actual size. It may take one or two days maximum for your foam mattress to return to its normal size after you open it.
