California King Platform Beds

California king platform beds are longer and slightly narrower than a standard king, which suits taller sleepers and bedrooms that are deeper than they are wide. Each frame supports the mattress directly on built-in slats or a solid deck, so no box spring is needed, and the collection includes modern, low-profile and headboard designs in solid wood and bamboo.

Not sure which long bed fits your room? Our King vs. California King guide compares the two, and king size platform beds show the wider alternative. Exact measurements for every size are on our mattress size guide.

California king mattresses and bedding are not interchangeable with standard king, so check sizes before ordering sheets, mattress protectors and toppers. For airflow under a natural mattress, a coconut coir bed rug adds a breathable layer between the frame and the mattress.

Modern Simplicity & Superior Support

A platform bed frame is the modern standard for supportive sleep. Designed with a sturdy wooden slat base, it eliminates the need for a bulky box spring, offering better airflow for your mattress and a streamlined aesthetic. Available in all standard sizes—from a compact twin to a spacious king platform bed frame—our beds cater to every room layout. By removing the box spring, you get a low platform bed look that feels grounded and spacious, perfect for contemporary or minimalist platform bed frame designs.

Sustainable Wood & Non-Toxic Finishes

Your bed frame should be as healthy as the mattress you sleep on. Our best platform beds are crafted from solid timber, avoiding the glues and formaldehyde found in cheap composite frames. We finish every wooden platform bed frame with natural linseed oil, ensuring a surface that is safe to touch and breathe around. This commitment to solid bed frames means you get furniture that is durable, eco-friendly, and free from the off-gassing associated with synthetic lacquers.

Platform Bed Basics

Frequently Asked Questions: Platform Beds

Does a platform bed need a box spring?

No. A platform bed frame is designed with a built-in foundation (usually wooden slats) that supports the mattress directly. This eliminates the expense and bulk of a box spring while providing superior airflow to keep your mattress cool and dry.

Can I use a regular mattress with your bed frames?

Yes, you can use any standard mattress with our platform beds. Our frames feature a solid wood slat system spaced 3 inches apart or less, providing the necessary support for memory foam, innerspring, or hybrid mattresses without the need for a box spring. While any conventional mattress works, we recommend pairing the frame with a natural cotton and wool mattress or a natural latex mattress to maximize airflow and maintain an eco-friendly sleep environment.

Are mattresses included with the platform beds?

No, mattresses are sold separately. Our platform beds are designed to be versatile and can accommodate a wide range of mattress types, including organic latex, wool, or cotton mattresses. This allows you to choose the mattress that best fits your comfort and sleep needs.

What materials are used in your platform beds?

Our wood platform beds are made exclusively from solid, sustainably sourced hardwoods like European Beech and American Oak. We do not use veneers or particle board. Each frame is finished with natural linseed oil, ensuring a non-toxic and eco-friendly surface.

What is the weight limit for these frames?

Our solid bed frames are engineered for high durability. While specific limits vary by size, a standard queen wooden platform bed frame is built to easily support a heavy organic mattress plus two adults (typically rated for 500+ lbs).

Do you offer headboards?

Yes. We offer a range of styles, from best platform beds with headboards for comfortable reading support to minimalist platform bed frames without headboards for fitting under windows or into tight spaces.

Do you offer storage options?

Yes. If you need to maximize space, check out our Captain's Beds collection. However, even our standard platform bed frames often have enough clearance underneath to accommodate rolling storage bins or drawers.

Are your platform beds compatible with Tatami mats?

Yes. Many of our frames are designed to work as Japanese platform beds. You can place tatami mats directly on the slats to create a firm, breathable surface for your mattress or futon.
