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.
  • 4-PIECE SPLIT DESIGN, FULLY ASSEMBLED - Unlike a single-piece or foldable mattress board support, this bed support board is split into four quarters for easier handling. Arrives fully assembled. Works with slatted beds and single support frames as a low-profile alternative to a box spring.
  • QUIET LOW-PROFILE BOARD FOR BED FRAMES Box springs add too much height, and regular slats can shift loudly and disturb your sleep. If you want a space-saving base that is also silent, this low-profile bunkie board is the perfect fix. Ideal for both platform beds and standard bed frames.

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/Full: 2-Piece Split Design Queen/King/Cal King: 4-Piece Split Design FOR TWIN AND FULL 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 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 I Needed
Excellent bunk board, sturdy and the right size. Seems well made and prompt shipping.

  • Works great!
Size: Twin(Set of 2) Style: New Version
These were a good deal and they are quality! I needed bunkie boards for my boys' bunk beds. I was tired of the mattress on the top bunk sinking in at the foot and a support rail broke on the bottom bunk. These fixed both problems perfectly and we're a very good deal!

  • It really works!
Size: Queen(Fold) Style: New Version
I have a platform bed with slats, but the slats weren't enough to keep my memory foam mattress from sagging, and my old back was killing me! Because I am older with a really bad back, I couldn't just go get plywood and cut it to fit, along with putting a smooth finish on it, and paying someone to do that would cost more than buying this bunkie board. I appreciate that the board is in two pieces that fold with hinges for my queen sized bed, because that meant I could install it by myself. It does raise the mattress above the platform more than I would like, but it's just an esthetic issue. The only bad thing is that I am seriously sensitive to scent, so I had to unpack it and let it offgas for a week and a half before I could stand it. But the first night I slept on it made it totally worth it! My back feels much better, and my neck too - I didn't even realize how bad my neck hurt until it got some relief! This is one of the best purchases I've ever made. My bed is stable and I sleep really well, along with reduced back and neck pain. Totally worth it! 👌 ... show more

  • Sturdy, Well Fitting, Secure Bunkee Board that Supports Mattress Well
Size: Queen(Fold) Style: New 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

  • So good!
Decided at 68 I’m too old to climb a step stool to get into bed! Ordered this to replace my box springs. Came timely, packaged well and fully assembled. It’s a little unwieldy for 1 person to manuever but fit my queen size bed frame perfectly and provides every bit as much support as the box springs. Highly recommend. ... show more

  • Excellent!
I love this! It was a two person job to put it in (king size) only bc the mattresses was awkward. As soon as I tried it out, I noticed a difference right away! Amazing! Highly recommend.

  • Very, Very poor quality!!!!
I got the bunkie board for my bed, the quality is so cheap and it doesn't support my mattress. I am trying to return it now both Amazon and Ups are giving me the run around.

  • Works great
Size: Twin Style: New Version
We loved the first one so much, we bought a second one a couple months later. It gives our bunk beds support while giving more headspace under the top bunk for our guests. It fit just perfect the twin bed size and was super easy to place since it comes in 2 pieces.
