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.
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. Learn More
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. Learn More
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" Learn More.
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 boxsprings to be more manageable when moving. Approx. width per person: 38" Learn More
Specialty Mattress Sizes
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. Learn More
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 boxsprings to be more manageable when moving.

4 1/2" x 5 1/2"
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 boxsprings to be more manageable when moving.

Foundation consisting of two different boxsprings. Can be standard or low profile height.
All king−size mattresses require split boxsprings for easier maneuverability. In these cases, two twin boxsprings are used. If you are moving a queen−sized mattress into a small living space, you may also require a split foundation ("custom queen").
Steel frame. Must have center support in King and Queen sizes.
LOW PROFILE FRAME
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/BOXSPRING
It is strongly recommended that you purchase a boxspring/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 BOXSPRING
Split boxes are foundations made up of two (2) separate boxsprings placed side-by-side, and are especially for delivery to places where a normal whole boxspring will not fit, such as through tight doorways, staircase or around narrow corners. All King size mattresses use Split boxsprings. Queen size boxsprings are available in two (2) types: Whole and Split boxsprings. Split Queen boxsprings 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 boxspring, you should make sure to order your Queen mattress with a Split boxspring. 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.
ADJUST YOUR WAY TO COMFORT
Whether you're watching a movie or responding to work e-mails, and adjustable base transforms your mattress so you can work, relax and play. If sinus pressure, back pain or a snoring partner is keeping you awake, simply adjust your bed with the wireless remote control. Based on your preference, you can raise or lower the base for premium lumbar support, or relax even deeper with a massage feature for your head and lower body.
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 boxspring/foundation. Because of the popularity of platform beds, more people are making mattress-only purchases than ever before.
