Queen size bed slats are used as a base for your mattress for a variety of reasons. Mostly, the slats replace a box spring, providing support and flexibility for the mattress, and are more durable than a box spring. It is not necessary to have a spring mattress when a good system of slats, support is in place. Slats for a double bed are the same size as the mattress itself.
Slats act as a base for your mattress, and are more common in futons, beds and bunk beds. A slatted base can be used in queen-size beds instead of a box spring. Lamas when purchased on their own are usually manufactured in a range of different sizes of wood grains and based on quality and durability. Battens are laid across the beds and evenly spaced to form the base. The slats rest on the outer edges of the frame of the bed and in the middle of the frame beam.
Queen size mattresses are 5 inches longer than their smaller double and full counterparts. The slats are found across the width of the bed, and are always 60 inches long. The width of each individual lath can vary depending on the design and grain of the wood. For the slats to fit them they cannot be any long or shorter than 60 inches.
