The Sleepwell Split Box Spring is designed for homes where a regular one-piece box spring is hard to move through. It comes in two separate pieces that fit together easily, making it a smart choice for tight stairways, narrow hallways, small doorways, condos, apartments, basements, and older homes.
Once placed together under the mattress, it provides the same strong, stable support customers expect from a regular box spring, while making delivery and setup much easier.

- Standard 7” Height: Provides strong support while keeping a comfortable bed height.
- Great for Tight Spaces: Ideal for narrow stairways, small doorways, tight halls, condos, apartments, and basements.
- Same Strong Support: Designed to support your mattress like a standard full-size box spring.

Important: This split box spring is ideal when a regular one-piece box spring cannot fit into your room. Please make sure both pieces are properly supported by your bed frame. Our team can help confirm the right setup.

How to Measure for a Mattress
-
Measure the inside width and length of the bed frame, platform or opening—not the outside edges.
-
Measure the available height and clearance, especially for RV bunks, hide-a-beds and truck sleeping spaces.
-
Measure at several points because custom spaces may not be perfectly square.
-
Note any rounded corners, angled edges, cut-outs or folding requirements. A simple drawing or photo can help us confirm your custom mattress.
