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/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.

  • Delighted this mattress support worked so well
This item made both sides of our old Ikea tubular metal double bed comfortable again. I jad been kind of rolling off the edge before placing it under the mattress. Now I feel like Im lying flat instead on on s slop. Simple but effective product. I bought the double bed size. The item has a wood frame all around each of the two sides. These frames are connected by a flexible plastic connector (top to bottom) that helps secure the two sides to stay straight on the platform or bed frame. ... show more

  • Excellent and sturdy!
This mattress base is lightweight but sturdy. It doesn’t slide under the mattress. It is breathable. Makes changing the sheets under my twin mattress a breeze because it doesn’t move when I lift the edge of the mattress. Fits perfectly in my twin bed. Still low profile and doesn’t elevate the mattress too much ... show more

  • Best buy for my King Mattress
I didn't want a box spring as I considered it old school. However, I realized I needed something so my king mattress doesn't hang through the slits of the bed frame. I was so happy to find this product. I purchased one for my son's bed and it fit perfectly. Months later I realized I need one for my bed. It's a little pricey but take the plunge! It's well worth it. I don't feel like the bed is sinking anymore as the support is perfect! It was easy to inbox and fold onto my bed. I used a measuring tape to make sure it fit as I thought I need to cali king but nope, the king fold was perfect. There's comments about the scent but to me, there's no scent otherwise than it smells like new furniture. ... show more

  • It works and I'm happy with it.
Size: Queen(Fold) Style: New Version
What can I say? It's a foldable Bunkie board that comes in two parts that each fold. I got the queen sized version to put on a metal platform bed because I needed something solid underneath the mattress to be able to put a shake-a-wake vibrator alarm underneath. It works, I'm happy with it.

  • Strong and true to size!
Size: Queen(Fold) Style: New Version
Love love love it! I got this for extra support because the wood slats felt like I was gonna brake them every time I moved! Super easy installation of course and it adds a little height to the bed so that's a plus for me.

  • Beneficial with limitations
Size: California King(Fold) Style: Old Version
I’ve had the bunkie support on a California King mattress with a pillow top mattress on top of the bunkie. After a few weeks, I’m feeling the wood slats. I’m going to rotate soon. I think there should be less space between the slats. But, if you use the bunkie actually under the mattress as opposed to my pillow top approach, this may not be an issue for you. I like the new support, but it has limitations depending on your use. Update 04/24 I have removed it from my bed. I have been having massive sciatica and foot numbness. I decided to sleep without this item. I am improving each day since getting off it. I suspect Bunkie bruises muscles and tissues Leading to inflammation and nerve impingement. The design is all wrong. The gap between the wood slats is too much. I believe my body couldn’t cope with the slat spacing. The two units I got for my King are sitting on the road waiting for bulk trash. It’s a shame. If they reduced spacing to no more then 1/2 inch per slat, it would still be transportable and helpful. ... show more
