Avocado Dark Brown California King Standard Foundation with Legs

Our standard foundation features four legs and supports up to 600 pounds. For more robust needs, our new Heavy Duty Foundation with Legs is engineered to support up to 2,000 pounds, with up to twelve legs and four crossbars (two in each direction) for extra reinforcement. Both versions are just as easy to set up and are 7.25" tall. Choose from dark brown 6.25" or light brown 7" solid wood legs. Compatible with any mattress.

Our Foundations are crafted from solid wood and wrapped in a durable cotton-poly woven cover. Both options offer a clean, seamless design that complements any bedroom style while supporting your mattress with care. And like everything we make, our foundations reflect our commitment to healthy materials and sustainable craftsmanship.

Each Avocado Foundation is built with a solid wood frame and reinforced for durability designed to replace a traditional bed frame. The Standard Foundation handles up to 600 pounds with ease. The Heavy Duty Foundation, on the other hand, is a reinforced powerhouse that supports up to 2,000 pounds. It's the ideal base for our Extra-Firm Mattress or any sleep setup where unyielding support is crucial.

Slatted support, spaced 3.25 inches apart, encourages airflow beneath your mattress — reducing heat buildup and extending its lifespan. Unlike outdated box springs that can sag or bounce, our foundations provide a stable, breathable base that holds up over time. Every foundation is backed by a 10-year warranty.

Fast. Simple. No tools needed. Both foundation types are designed for straightforward, stress-free setup. Just lock the outer rails together, insert the pins, install the center or cross supports, and roll out the slatted top. Done in minutes no extra hardware required.

Your mattress is only as strong as the base beneath it. For optimal performance especially with heavier or firmer mattresses your foundation must distribute weight evenly to preserve comfort and structural integrity. Our Heavy Duty Foundation is engineered with that in mind. Whether you're a larger sleeper or just want peace of mind, you’ll get the durable, sag-resistant support your mattress needs to last longer and feel better.

Choose from two heights: our standard profile (7.25") or low profile (3.5")  both available in either Standard Support (up to 600 lbs) or Heavy Duty Support (up to 2,000 lbs). Shown here with our Metal Bed Frame (sold separately). Need a standalone bed frame? Try our Foundation with Legs. Compatible with any mattress.

Our Foundations are crafted from solid wood and wrapped in a durable cotton-poly woven cover. They offer a clean, seamless design that complements any bedroom style while providing effortless support for your mattress. And like everything we make, our foundations reflect our commitment to healthy materials and sustainable craftsmanship.

The Low Profile version stands 3.5 inches tall, making it ideal for taller mattresses or a more modern, minimalist look. It’s perfect for those who prefer a lower bed height or have limited vertical space. The Standard Profile, at 7.25 inches tall, offers a more traditional bed height — ideal for lower-profile mattresses or anyone looking to add height and presence to their bed.

Slatted support, spaced 3.25 inches apart, encourages airflow beneath your mattress reducing heat buildup and extending its lifespan. Unlike outdated box springs that can sag or bounce, our foundations provide a stable, breathable base that holds up over time. Every foundation is backed by a 10-year warranty.

Our foundation is GREENGUARD Gold Certified by UL Environment for low emissions, just like each of our mattresses. That means they meet acceptable standards for emissions.
