A mattress cannot rest on an uneven surface, such as bed slats. It must be a flat surface that acts as a shock absorber that will dissipate weight and stress evenly. Choosing the correct foundation is based on the type and style of your bed as well as performance preference.
There are three types of support: the standard box, the bunkie board and the adjustable base.
Standard Box Spring
- Wood or metal frame, with a dust cover around it.
- Choice of 9” or 5” height depending on mattress thickness and style of bed. Integrity and strength are equal for both sizes. Both
sizes are priced equally.
- Split kings are standard, but split queens are available for tight spaces. There may be an additional cost for these.
- Used on metal or wood bed frames.
- Thin piece of plywood covered with foam and fabric, 2” in height.
- Typically used with a very thick mattress or when on a storage bed, when a standard box would be too high.
- Available as a split queen for tight spaces.
A series of connected wood or metal bars that lie across the width of a bed frame. Acts as a foundation if the slats are less than a few inches apart. Otherwise an additional support is required.
- Electronic moving base that raises the top and bottom of a mattress (head and feet) to relieve body pressure.
- Puts you in a natural anatomical position (zero gravity) which allows for easier breathing, better blood circulation and pressure relief on the back, hips, shoulders and neck.
- Some models provide muscle stimulation and a lumbar support.
- Can be used on any bed.
No Foundation or Additional Support Required
- A true platform bed with a built-in plywood support is the only bed that does not require a mattress support.
