Twin Bed

Although the word twin bed bring in the image of two beds, as in twins, it is usually defined as "one of a pair of identical beds". It is considered to be one of the most preferred bed for children's room or rooms with multiple occupants. Twin bed is commonly used by kids and is the first bed most of the kids get after switching from the crib or toddler bed.

The bed is basically designed in such a way that it can be stacked and conveniently turned in to bunk beds, if required.

Twin Bed Mattress

A mattress as we know is a mat or pad, placed on top of a bed, upon which we sleep or lie. The term mattress comes from Arabic words meaning "to throw" and "place where something is thrown" or "mat, cushion." Twin bed mattress usually comprises either an inner spring core or materials including latex, viscoelastic, or other polyurethane-type foams. It can also be filled with air or water, or a collection of natural fibers, like futons. Depending on the manufacturer, the quality of the bedding, and the robustness of use, the life span of the mattress varies. However, on an average a good quality innerspring mattress should last between 7 and 10 years and the memory foam and latex models should last somewhere between 10 and 20 years.
