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.

  • Exactly what we needed
Size: Twin XL(Set of 2) Style: Old Version
These boards did the trick to help our bed out. We were struggling to get a firm enough sleep using our sleep # bed & a bedframe that didn't work with the clunky base that came w our sleep number bed. Looked at these & thought that would work just as solid without all the bulk of the base that came w the sleep number bed (c5-older version). These were perfect, right support, small & thin enough, lite weight and easy to maneuver and solved our problems! Best $ spent ... show more

Works as it should. Good value. Bought for a child's room and had held up well a year later.

  • Lightweight Support, 2 Pieces
Size: Twin Style: Old Version
Ordered regular twin size to support a 14" mattress. Due to the height of the mattress, I did not want to add another 8+ inches for the box spring/support. I was afraid this would be two cheap to support the mattress with my weight combined, but I have been able to lay on it without issues. My boyfriend and I were also able to lay on the mattress together atop of this support with no cracking or groaning of the wood! Functions as described and arrives in one thin package as two separate panels. They lay right into the frame with not additional adjustment needed. Easy to set up and so far, no complaints! ... show more

  • Watch the fit
Size: Twin Style: Old Version
Good product to use as a foundation, however we got the twin size and it was a little too small to fit better on the width

  • It’s very sturdy!
Size: Twin Style: Old Version
It’s easy to assemble and it’s hardly noticeable. I’ve been needing a new board and I’m glad I went with this one! It fits perfectly under my mattress and even though it’s two pieces, it doesn’t clash badly like the cheap ones you can buy.

  • Split is it's weakpoint.
Size: Twin Style: Old Version
It does it's purpose of working under the mattress. If there is a border around it like pictured it works as it should. However we don't have a bordered bed and every time we worry is the split coming off of each other. I have had my child slip with the mattress because the middle part would split. So I wouldn't fully recommend a 2 piece ... show more
