Bed Information Sheet
Mattress Sizes – Width and Length

Mattress and box spring sizes are standardized in the USA and Canada based on the following
dimensions:








                      

            


All of the bed frames we offer can be supplied to accommodate any of these mattress sizes.  We can also
supply bed frames for custom sized mattresses.

Bed frames consist of a head board, a foot board, 2 side rails and a set of slats to support the box
spring.
 A Twin, Full and Queen mattress usually come with a single box spring.  King mattresses
usually come with two box springs, therefore
slats for King beds include a center support.  If a Queen
mattress has two box springs, a slat center support should be specified when ordered.

Mattress and Box Spring Heights

Mattress and box spring heights are not standardized and will vary by manufacturer and mattress
style.
 Mattress heights can vary from 8” to 18”, and standard box spring heights can vary from 8" to 12”.   
“Bunkie boards” with heights of 1.5” to 2.5” are also available to be used in place of standard box springs.
Bed Frame Dimensions
The width and length of bed frames are designed to accommodate standard mattress sizes with some
clearance around the head, foot, and sides of the mattress to accommodate bedding.

Headboard (HB) heights will vary by individual bed designs. Footboard (FB) heights also vary by bed
design and typically run 55-65% of the headboard height.
 Bed frame headboard and footboard heights
can normally be adjusted as required.

The position of the side rails are measured as the distance to the bottom of the side rail from the
floor.
 The side rail height is either set for a box spring and mattress (standard height) or at a higher
position (platform height) to accommodate a trundle or under bed storage.  These side rail settings are
normally the same within bed frame collections. Typical side rail setting for some of our bed frame
collections are:

Bottom of Side Rail: Distance to Floor
To determine the height of the mattress from the floor for a bed frame:

Top of the mattress to the floor = H (bottom of side rail) + side rail lip (1")
+ slat thickness (3/4”) + Box spring height + mattress height

Side rail positions can usually be adjusted up or down as required.
When only a headboard is preferred for a specific application, the headboard is usually attached to a
metal frame which is used to support the box spring and mattress.

Unfortunately, the metal frame bracket used to attach the headboard is not large enough to firmly secure
a tall headboard; therefore, the headboard tends to wobble.
Taller, wider and heavier headboards
frequently have to be attached to the wall.

As an alternative to using a headboard attached to a metal frame, most bed frames can be supplied with
a low profile footboard
.  The height of a low profile footboard is about 1” higher that the top of the bed side
rails.  It is designed to be just high enough to support the side rails. The result is a solid bed frame which
can support the slats, box spring and mattress.

For platform applications, the low profile footboard is higher to accommodate the higher setting of the side
rails.  The height of the a low profile footboard can be adjusted as required for different side rail settings.
