Mattress Sizes: Full

Full

Full, or "double", mattresses are a great solution for your child's bedroom, as the extra width compared to a twin mattress gives your child more room to stretch as he/she continues to grow. Full mattresses can also work in guest bedrooms where a queen mattress is too large to fit, since two people can often fit on a full mattress (although Queen mattresses are ideal for a guest room).

Serta produces a wide variety of full mattresses featuring both innerspring and all-foam support systems.

A Serta full mattress measures approximately 53" x 74.5". These measurements can vary by +/- 1/2". Size availability varies by product and retailer. Mattress heights vary by product, so please see your retailer for information on specific model height.
