Restonit 2-Inch Low Profile Posture Board Foundation (Boxspring)

Give your mattress the stable support it needs while keeping your bed at a comfortable low height with the Restonit 2-Inch Low Profile Posture Board Foundation (boxspring). Also known as a bunkie board, this ultra-low-profile foundation is designed to create a flat, rigid surface beneath your mattress without the added height of a traditional 4-inch or 7-inch box spring. The listing gives it an approximate height of 1.75 inches, making it an excellent option for beds where a full-size foundation would make the mattress sit too high.

This posture board is especially useful with foam and memory-foam mattresses. Foam mattresses need even support across the full surface to help prevent sagging into wide gaps between bed slats. By placing the posture board under the mattress, you can create a more uniform, non-flexing foundation on platform beds, daybeds, bunk beds and other frames with widely spaced slats.

The slim design also makes this foundation a practical choice when you want to preserve the look of a lower-profile bed while still providing the mattress with a solid support surface. It can also be used on top of an older box spring when a mattress requires firmer, more even support than the existing foundation provides.

Available in a range of standard and split sizes, the Restonit Posture Board helps make mattress setup easier in rooms with tight stairways, narrow hallways or bed frames that need a lower overall height. Choose the appropriate size for your mattress and bed frame for a clean, supportive foundation solution.
