MATTRESS SIZE GUIDE
Individual comfort is key when deciding the right size mattress. Let us help you discover the many other factors that contribute to finding the perfect mattress to fit your room and your comfort needs.
Crib Mattress Measures 5" x 27" x 52"
Crib mattresses should be no more than 6" thick by law, and should fit snugly into the crib frame. For little one’s safety, the space between the mattress and the crib should be no more than the width of 2 fingers. These mattresses are typically very firm.
Twin Mattress Measures 39" x 75"
This is the most common size found in children's rooms, and is used on daybeds, trundle units and hideaways. The width of a twin mattress (39") is the minimal amount of space needed for a single person to lie comfortably each night.
Twin XL Mattress Measures 39" x 80"
Twin XL, or extra long, is the most common mattress size found in college dorms. The additional 5" in length (compared to a twin sized mattress) accommodates taller sleepers. Twin XL mattresses fit comfortably in smaller rooms because they take up minimal space.
Full Mattress Measures 54" x 75"
Full size beds are 15" wider than Twin beds and 5" shorter than a Queen bed. This size is a good option for a guest room or as a child's step-up mattress.
Queen Mattress Measures 60" x 80"
Currently the dominant size bed in America, Queen Beds are 6" wider (and 5" longer) than a Full size bed. These added inches can make all the difference in comfort, but each adult still has 9" less than the width of a standard Twin bed. However, it's a good choice for guest rooms and smaller master bedrooms. Can use standard pillows or the slightly larger queen size pillows. Approx. width per person: 30"
King Mattress Measures 76" x 80"
King beds are growing in popularity. King is about 16" wider than a Queen bed. Both are about 80" long. The Eastern King is the only bed to give each person the same width as a Twin bed. In fact you can push 2 Extra-Long Twin beds together to be the same size as an Eastern King. This is a good way to have a versatile guest room (use 2 twins separately or push together to make a king bed for couples). An Eastern King bed comes with one mattress and two half-width box springs to be more manageable when moving. Approx. width per person: 38"
California King Mattress Measures 72" x 84"
California King is 12" wider than a Queen bed but adds 4" in length. This may be a better choice for taller adults. This size is sometimes known as the "Western King". Bedding may be labeled either "California King" or "Western King". A California King bed set comes with one mattress and two half-width box springs to be more manageable when moving. Approx. width per person: 36"
There are so many ways to stay supported, and the right foundation is the best way to keep your mattress in great shape for years to come. The foundation is the ying to the mattress’s yang. They just work better together. Find the foundation that best matches your mattress and your space needs.
Standard Profile Box Measures 8" x 9" High
The standard profile box is the most common height for a foundation.
Low Profile Measures 4½" x 5½" High
If a standard box−spring makes your bed too high to get into and out of easily, a low profile box−spring may be desired. Low profile foundations will also keep your mattress from covering a low−sitting headboard.
Split Foundation Can be Standard or Low Profile Height
All king−size mattresses require split box−springs for easier maneuverability. In these cases, two twin box−springs are used. If you are moving a queen−sized mattress into a small living space, you may also require a split foundation ("custom queen").
Standard Frame Measures 7¼" High
Steel frame. Must have center support in King and Queen sizes.
Low Profile Frame Measures 4¼" High
Steel frame. Lowers height of mattress so as not to cover a low−sitting headboard. Also makes it easier to get in and out of the bed.
THE IMPORTANCE OF THE FOUNDATION/BOX SPRING
It is strongly recommended that you purchase a box spring/foundation that is specially designed to match your new mattress. A mattress and foundation are engineered to work together as a set, and the foundation takes a lot of the nightly wear and tear, and contributes to the bed's overall comfort and support. Putting a new mattress on an old foundation, pairing it with a foundation it wasn't designed to work with, or adding a board between the mattress and foundation will impede comfort and reduce the useful life of your new mattress. It may also affect the manufacturer's warranty.
WHEN YOU MIGHT NEED A SPLIT BOX SPRING
Split boxes are foundations made up of two (2) separate box springs placed side-by-side, and are especially for delivery to places where a normal whole box spring will not fit, such as through tight doorways, staircase or around narrow corners. All King size mattresses use Split box springs. Queen size box springs are available in two (2) types: Whole and Split box springs. Split Queen box springs are two 30 inch X 80 inch boxes that equal the size of one (1) whole Queen. If you think you will require a Split box spring, you should make sure to order your Queen mattress with a Split box spring. This can be found in the size selection under (Split Queen Set) or (Custom Queen). Only order split boxes if necessary, since they cost more than a 1 piece box.
IF YOU HAVE A PLATFORM BED...
Platform beds are a very popular style of bed today. They are frames, typically with a solid platform or wooden slats across it for the mattress to rest on. They are relatively low to the ground, and do not require a box spring/foundation. Because of the popularity of platform beds, more people are making mattress-only purchases than ever before.
