Features

  • 1. Corrugated Structure For High-Strength Support: This bunkie board features a unique corrugated structure with high density and strong load-bearing capacity, easily supporting up to 600 pounds (about 273 kg). It also reduces noise between the mattress and the bed board - ensuring you can sleep peacefully without the squeaks and noises common in wooden mattress support boards.
  • 5. Protect The Mattress: Placed between the mattress and the bed frame, the corrugated board design ensures even weight distribution and effectively prevents to the mattress from sinking. It is suitable for all types of mattresses (memory foam, hybrid mattresses, spring mattresses), preventing them from sinking into the gaps of the bed frame and extending their service life.
  • 6. Foldable Design - Easy Assembly: No tools are required, just unfold it, and the Velcro connection between the two boards can be easily placed on the bed. The lightweight and sturdy structure makes it easy to store when not in use, perfect for seasonal furniture, small spaces, or quick room rearrangement.
  • 7. Breathable Polyester Fabric For Improved Comfort: This bunkieboard uses a surface polyester that is anti-stain, and a non-woven lining to promote air circulation, and keep the mattress dry. The fabric structure seamlessly fits the contours of your mattress and is quick-drying, making it ideal for humid climates.
  • 8. Compatible With Bed Frames Of All Sizes: It fits most brand bed frames on the market, but is slightly smaller than the standard mattress size. This is because some beds have a raised frame to prevent the mattress from sliding, but the bed board cannot fit in at the same time. Therefore, we simultaneously reduced the size of the bed board during the design, so that any bed frame can be adapted. It does not affect the use, and is superior to traditional slats in terms of durability and stability. For sleepers who seek long-lasting support without compromising comfort, this bed board is a must-have product.
