Features

  • 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.

O……M…..G…… If I could give more than 5 star reviews to what it did to my bed I would…. And I’ve only been able to lay in my bed for 5 minutes since getting it under my mattress…. OK, so I had an 18 inch mattress with a regular frame bed and it was supposed to be a box spring mattress mattress pad all in one…. Well when getting it this bad mattress had way better reviews than I was receiving because I was waking up feeling like I had been in a fight every night…. So after some weeks of sleeping on it, I ordered an additional mattress pad, thinking that it would help, and the memory foam mattress pad was not memorizing anything that touched it. Not only that I realize that every time I sat on my bed, it was like sitting on a seesaw because it would move. So obviously, I had no support at all underneath my bed like I thought I did…. A few weeks later, I started searching for something to give support, but not the truth thickness of a boxspring because between the mattress and the memory foam, I was already at 21 inches and really couldn’t have that much more height added to my bed, but new I needed stability under mattress. That is when I found this amazing product and when I tell you guys within five minutes of installing this and me laying on my bed because I haven’t been able to go to bed yet my memory phone was memorizing, my handprint my body, and I felt the true softness and firmness of my mattress like it was reviewed when I ordered. Needless to say, I made a quick dinner did an everything shower and I am so excited about going to bed tonight.!!! 100% recommend if you have one of those thick mattresses that’s supposed to be all in one to give you the support underneath that you’re gonna need. It’s almost like I have an entire new bed. And now…. It’s time for bed nighty night finally got a full nights rest I have been longing for! ... show more

  • Easy and it does the job
This was perfect for my son’s conversion bed. It was the kind that starts as a crib, then converts to a toddler bed, then a full bed. We just needed this plus a mattress and we were good to go!

  • The best i've tried
The best bunkie board i've tried bar none. I've tried the fabric covered accordian style wood slats, and i've tried other wood platform bunkie boards from other manufacturers before and none of them felt as sturdy or stable as these. I'm heavy, and there was a noticeable improvement in the support and quality of sleep after putting this on the bed. I will most likely end up getting a queen sized one too! ... show more

  • Perfect for bunkbeds
These are great for a bunk bed. The mattress lays on them perfectly since most bunk beds have slats for the mattress. Great price.

  • Good support
I ordered this to put under my Temperpedic mattress because it was not being supported enough by my metal frame. This made a world of difference! It has totally changed the feel and amount of support that I get now! The only thing is that description says it is metal but it is wood. However I am still very satisfied with this Bunkie board and would highly recommend! ... show more
