This foldable bunkie board creates a stable, supportive base for your mattress to help reduce sagging and improve comfort over time. High-strength PP panels and an Oxford fabric bottom provide durable construction with a quiet, non-slip design. Hook-and-loop straps help keep the board securely positioned on the bed frame. Its slim 0.4" profile fits between the mattress and frame without noticeably raising bed height. The foldable design also makes it easy to store when not in use.
