Twin     Mattress Dimensions
Twin Mattress Dimensions - 39in Wide x 75in Long: Twin Mattresses are the perfect size for your children's room or a guest room. Just because a room is short on space doesn't mean that the mattress can't be comfortable. Add on a twin sized memory foam mattress topper to make sure your guest is comfortable. Or, instead of purchasing a separate piece, you also have the option to purchase your twin mattress with a mattress top (not to be confused with a mattress topper). Mattress tops on Wayfair are available in four variations; tight top, pillow top, euro top, and memory foam top. View the twin mattress page to see the differences between them!

Full mattresses are a very popular size, and can be a great pick for guest bedrooms that have extra space. Why buy a full size mattress? For one, it's cheaper than going bigger. Queen and king size bed sets are known to be pricier, in some cases much pricier than full size. A second reason is you don't want to spend a fortune on dressing up your bed either, right? Luckily, full size bedding is also cheaper than its bigger alternatives, and widely available.

The dimensions and thickness are regulated by the Federal government, but regardless, you'll find different size ranges wherever you go.
