About this item

• ZIP-CONNECTED SUPPORT FOR KING BEDS — Unlike loose two-piece bunkie boards, this king bunkie board joins two foldable panels with a zipper to reduce center separation. Four straps and anti-slip dots keep the support aligned.
• 10MM SUPPORT ACROSS A LARGER SLEEP SURFACE — High-density hollow-core panels bridge slat gaps for flatter mattress support across a king bed. This mattress support board holds up to 440 lb and helps reduce sagging and unevenness.
• LIGHTWEIGHT, BREATHABLE & QUIETER — The moisture-resistant hollow-core bed support board promotes airflow without adding bulky height. Its 600D Oxford cover reduces frame friction, helping the mattress board stay quieter during nightly movement.
• KING SIZE BUNKIE BOARD 76 X 80 IN — These bed boards for under mattress fit frames with slat gaps up to 10 in. Compatible with foam, hybrid, latex and innerspring mattresses on platform, metal and slatted beds.
• TOOL-FREE, FOLDABLE SETUP — Unfold the two panels, connect the zipper, secure four straps and replace the mattress. This under mattress support board folds for easier carrying and storage in bedrooms, guest rooms, RVs or during moving.
