Features

  • Breathable Stitch-bond Fabric
  • STURDY SUPPORT TO PREVENT SAGGING A sagging mattress can ruin your sleep. This firm supportive bed board keeps your mattress flat and even, stopping dips and lumps before they start. Enjoy a comfortable, well-supported bed that helps you wake up feeling rested.
  • EXTENDS MATTRESS LIFE & SAVES YOU MONEY Mattresses arent cheap... and a mattress without support wears down fast. This strong bunky board keeps everything firm and even, preventing premature wear & tear. Protect your mattress, sleep better, and avoid having to replace it too soon.
  • STRONG VENTILATED WOOD FOUNDATION Built from 1.5" thick split wood with a slatted design, these bed boards for under mattress provide a sturdy foundation that supports heavy weight. The stitched fabric cover adds breathability and reinforces durability, perfect for heavier mattresses.
  • 2-PIECE SPLIT DESIGN, FULLY ASSEMBLED - Unlike a single-piece mattress board support, this bed support board is split into two halves for easier handling. Arrives fully assembled. Works with slatted beds and single support frames as a low-profile alternative to a box spring.
  • PERFECT FOR BUNK, LOFT & DAYBEDS Box springs can add too much height, and regular slats can shift loudly. If you want a space-saving base that is also quiet, this low-profile bunkie board is the perfect fix. Ideal for kids' bunk beds, loft beds, and daybeds.

Description

A STURDY FOUNDATION FOR BETTER SLEEP A mattress is only as good as the support beneath it. Without a solid base, it can sag, wear out faster, and leave you waking up sore. This fabric-covered bunkie board creates an evenly firm foundation that extends mattress life, prevents sinking, and makes it feel more comfortable. Designed for both strength and breathability, it features a 1.5-inch thick wood slat frame wrapped in durable stitch-bond fabric for airflow and stability. Unlike bulky box springs or flimsy slats that shift around making noise – this no-sag, split-design bunkie board keeps your mattress supported day and night. Arriving fully assembled for easy transport, it makes setup easy and fits perfectly into your existing bed frame. Whether you need low-profile support or a replacement for loud wooden slats, this bunkie board delivers comfortable stability without the extra weight. PRODUCT SPECIFICATIONS: Usage: Under Mattress Support Thickness: 1.5 inches Material: Solid Wood (Slatted Frame) Covering: Breathable Stitch-Bond Fabric Twin/Twin XL/Full/Queen/King: 2-Piece Split Design Full/Queen/King/Cal King: 4-Piece Split Design FOR TWIN, TWIN XL , FULL, QUEEN AND KING SIZE BEDS 2-piece split design for Twin and Full sizes. Lightweight and easy to maneuver in tight spaces. Perfect for children’s bunk beds, loft beds, and daybeds where a box spring would add too much height. FOR FULL, QUEEN, KING AND CALIFORNIA KING BEDS 4-piece split design for Queen, King, and Cal King sizes. Provides sturdy support for bigger mattresses. It works great for standard bed frames that need extra strength, helping to stop sagging early and keeping your mattress firm and comfortable longer.

  • NEVER KNEW THESE EXISTED
I got a new mattress but didn’t need a box spring and my cat likes to claw the bottom so I posted on FB and asked if there was anything like a box spring but “not.” Anyway this is the best. Protects your mattress and I don’t have to worry about it ever sinking as well.

Obtained sleigh bed. Had to ditch box springs due to bed being too high. Immediately could tell difference in mattress that I have loved. Purchased these bunk boards which made all the difference and I had my bed back!

  • Sturdy, Well Fitting, Secure Bunkee Board that Supports Mattress Well
Size: Queen(Fold) Style: Old Version
Purchased this Bunkee board to support my queen memory foam mattress that’s sits on a metal frame . Shipping was delayed, hence the 4/5 rating. However delivery person was nice , super helpful. Very easy assembly, unfolds into two piece portable, low profile pieces that lie next to each other directly on the frame. This was not the cheapest choice but it is wood construction , covered by fabric that feels very sturdy and did not shift or make noise with both myself and 200 pd husband on . So far, so good. Will update if this changes. ... show more

  • Broke in half
Size: King(Fold) Style: Old Version
We’ve only used it for about 3 weeks on our king size bed frame and it snapped in half where it folds! For $170 this is cheap quality. I do not recommend. The only good thing is that Amazon was willing to replace it without having to return the broken one. Hopefully the replacement holds up.

  • Thick.
Size: Queen(Fold) Style: Old Version
Salesman at store said this was required for the bed I purchased. Turned out when I put the bed together, this was not necessary and would have added an extra 1-2 inches in hight to the bed. On an already tall bed. So in storage they went.
