Durability & quality

I've never assembled a box spring before, and it seems sturdy for this price point. I ordered the twin size, and was able to put it together by myself except for one step - I wanted to stretch the slats all the way to the edge of the recessed area so the straps would be taut. Consider wearing gloves for assembly, lots of splintery wood. My only suggestion for the seller is they should put an extra of each of the smaller hardware bits just in case they got lost.

This product is designed to provide excellent support under any mattress. It ships in a compact box and can be easily assembled in minutes — without any tools! Unlike traditional box springs, our foundation can be broken down quickly if you’re moving or need to maneuver around tight corners. A Casper Foundation ensures that mattresses, sleep as they should. Some older box springs or foundations don’t provide a solid surface, causing mattresses to sag from the support breaks. Our Casper Foundations slats are positioned a perfect four inches apart for optimal support. A strong and level foundation helps mattresses perform at their peak for a decade or more, no matter what kind of bed frame they sit on. Casper Foundations and mattresses are the perfect pair. We spent over a year developing the Casper Foundations, so its design has the same considerations as our mattresses.

Easy to put together. Very sturdy. There are screws heads in the bed frame in 3 places down the middle of the frame and the center piece of the foundation sits on the screw heads. So it doesn’t fit flat on the frame. Either the makers of the bed or the foundation need to accommodate this space for the screw heads. I coved the foundation with a fitted sheet since it only comes in one dark color.. Doug. Erie, MI. Wed Jun 24 2026

I should have bought this when I bought my Purple mattress 5 years ago! Using a regular box spring under a Purple mattress will cause the grid to lose its shape and creates valleys in the mattress. Placing the Bunkie Board on top of the box spring restored the grid to its natural shape, and NOW I sleep on the mattress just like I did when I got it home! I'll be buying these for EVERY SINGLE Purple mattress I own!!!. Yokasta. NM. Mon Oct 19 2026

Sturdy and quiet. Easy assembly. Pamela. Pomona, CA. Mon Jul 06 2026

This bunk was the perfect thing for our king size bed. I wanted to get rid of our boxspring and I replaced It with this. Very strong and gives the added support to our mattress needs. If you need support without the height of a boxspring this is a great option.. Candi. NY. Fri Oct 16 2026
