Bed Size Dimension Guide

The size of a double xl mattress is nominally 54 inches x 80 inches but will sometimes be as much as 1-2 inches smaller in each dimension. Double XL provides you with five extra inches in length than a regular double so it will be great for taller people or couples, who prefer to sleep really close or maybe just don't have room for a queen. We’ll custom make your next mattress any size you want.

There are many factors that will determine the size of bed you can fit into a bedroom such as:

• door locations that could make much of your wall space unusable.
• window locations that can interfere with furniture or cause drafts.
• uneven ceiling heights that can reduce your usable square footage.
• placement of electrical, cable, HVAC vents and phone outlets.
• additional furniture that you may wish to place in the room including, night stands, chests, desks and dressers.
• Keep in mind that if you’re adding a headboard or complete bed to your new mattress set (and not just a steel support frame) this will add to the overall dimensions shown in this guide by two to ten inches.

• Steel bed frames needed to support each size of mattress set to properly maintain your warranty:
• It’s important to read the fine print of your mattress set warranty in order to purchase the correct frame, particularly so if you’re supporting a queen size set that requires the extra centre support
• Steel frames come in two styles. One with the shown wheels and a second with glide-cones (not shown but recommended for hardwood).

• Very few manufacturers make foundations with springs inside any more as costs have risen and there was little evidence that it increased the comfort or life span of the mattress above it. There are still some foundations that feature a very stiff wire grid just under the box spring’s top cover while others are manufactured with wood side supports and a solid wooden platform right underneath that same top cover.
