My partner and I have been using this split frame for a few months now and we love it. This is our first hollow box spring after living with an old coil box spring for so long. Though there are definitely differences, we sleep just as well on it. For reference, the two of us on our queen double pillow top mattress with four additional mattress tops are roughly 650lbs all together. This split frame easily holds all of the combined weight. We live in a second floor condo with a winding staircase and this split frame was easy to maneuver up both sets of stairs.. Remi. Ohio. Mon Jan 19 2026

I’m very disappointed with this purchase. The box looks like it should be good quality, but unfortunately it arrived in poor condition. I contacted customer service to report the issue, and while they offered a 20 discount, I asked for a bit more since I really don’t want to go through the hassle of returning it, buying another one, and waiting again for shipping. They asked me to wait 24 hours for a response, so I’m still hoping for a better resolution. This is actually my third recent order with problems, which is very frustrating. I’ve been a Wayfair customer for years and never had this many issues before. Really disappointed with this experience. I received an email from Wayfair saying they are going to credit back to my original payment method, which I appreciate. I already finished building the box spring and, as I mentioned before, it does look like good quality overall. I really hope I won’t have any problems with it later on. I’ve been a loyal customer for many years, so I’m hoping this issue was just an unfortunate experience.. Veronica. Jacksonville, FL. Tue May 05 2026

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.

The Upholstered Metal and Wood Box Spring has the best of both worlds: a look that polishes off your bed and the strength and durability of a bed foundation. Crafted to look good enough so that you can forgo the bed skirt, it’s made tough on the inside with a steel and plywood framework and clean on the outside with woven grey fabric paneling. A set of wooden slats over the top completes the finish and supportive design, so you can rest easy on a latex, memory foam, or spring mattress. Our favorite part is that it ships straight to your door in one slim box and only takes five simple steps to put together. All of this, plus a 5-year worry-free warranty and a more-than-affordable price tag. We can’t think of a better partner for your mattress.
