Mattress Foundation - Final Sale
The Amerisleep Mattress Foundation is an 8.5-inch bed base designed to replace your box spring, assembles in minutes with no tools, and fits perfectly with our memory foam and hybrid mattresses. For this closeout sale, we’re offering 50% off our remaining California King size inventory.
We built the Amerisleep Platform Bed Frame as an all-in-one bed base that delivers solid support and modern style for your bedroom. We use durable hardwood for the side rails, center supports, and slats. Plus, our platform bed’s slats are extra-wide to ensure your mattress never sags. Best of all, the entire platform bed frame assembles in minutes with no tools required.
The Amerisleep Mattress Foundation follows standard bed sizes with an 8.5-inch height. That means it should fit in any standard bed frame. But you can also use our Foundation without a frame and show off the sleek charcoal grey upholstery.
The hardwood slat system
Too many bed frames develop "soft spots" over time that cause your mattress to sag. This leads to discomfort and faster mattress deterioration. That won't happen with the Amerisleep Platform Bed Frame. Instead of using a bunch of thin slats, we equip our platform bed with thick hardwood slats spaced to provide even support. We reinforce our slats with center supports to keep you and your mattress sufficiently supported no matter how much you toss, turn, or move about the bed.

Find answers to the most common questions about our Amerisleep Platform Bed Frame.
You do not need a bed frame with your mattress, as many mattresses can be placed directly on the floor, but we do recommend them. Placing your mattress directly on the floor can lead to dirt and moisture build-up, resulting in premature wear and tear. Plus, it makes it hard for air to escape, which can lead to night sweats and overheating.
While box springs were once popular, they’re now a less desirable option, as they’re not compatible with foam beds. Foam beds need a solid or slatted foundation or platform bed frame to rest on, so they work best with more modern mattress bases. Hybrid mattresses are also best supported by solid or slatted foundations or bed frames, whereas innerspring mattresses can work with box springs or modern mattress foundations.
Box springs provide bouncy, sturdy support for your mattress through a combination of coils and wood slats. Platform bed frames are either slatted or solid and do not contain coils, so they provide more even support than box springs.
Box springs are best suited for innerspring mattresses, whereas all other mattress types are best supported by more modern mattress bed bases.
You can put a mattress directly on a slatted foundation or platform bed base, but you’ll want to make sure the slats are close enough together to provide even support. As a general rule of thumb, slats in a slatted foundation or bed frame should be no more than 3 inches apart.
If your slats are spaced further apart, we recommend two solutions: 1) buy additional slats to fill the gaps or 2) buy a bunkie board to place across the slats, creating a solid, flat surface. You can also opt to buy moisture-resistant ply-wood instead of a bunkie board.
You do not need a headboard with a platform bed frame as many of them are stand-alone mattress accessories.
We recommend placing no more than 750 pounds on our Amerisleep Platform Bed Frame.
No. Our Platform Bed Frame is an all-in-one mattress support system and bed frame. It’s larger than a box spring or foundation and does not fit within other frames. Additionally, the foundation’s legs are part of the frame and cannot be removed.
Yes! We back all of our platform beds with a 1-year warranty covering manufacturer defects, including defects with the bed’s fabric upholstery.
Mattress accessories, such as sheets, pillows, and bed bases, do not qualify for the 100-night trial and are non-returnable.
