Browse Our Wide Selection of Beds, Chairs & More
A king bed gives you the most sleeping space of any standard size, which makes it ideal for couples, light sleepers and anyone who shares the bed with kids or pets. This collection gathers king size bed frames in a wide range of looks, from tufted and channel-stitched upholstered beds to solid wood, rattan and metal frames.
Many designs are platform beds with built-in slat support, and many come with a headboard, so you can set up the whole bed in one step. Some styles add storage drawers, LED lighting or a mid-century profile. Matching king headboards are here too if you want to update a frame you already own.
Every frame is sized for a standard king mattress, about 76 by 80 inches. If you have a California king, which is longer and narrower, see our California King collection. Overall frame dimensions vary, so check each listing for exact measurements and what is included.
Frequently asked questions
How wide is a king size bed frame?
A standard king mattress is about 76 inches wide and 80 inches long, so a king bed frame is usually around 76 to 82 inches wide once rails and the headboard are included. Exact width depends on the design. Measure your room and check each listing's overall dimensions before you buy.
What is the difference between a king and a California king bed?
A standard king mattress is about 76 by 80 inches, while a California king is about 72 by 84 inches. The California king is 4 inches narrower but 4 inches longer, which suits tall sleepers. The two are not interchangeable, so choose a frame that matches your mattress size exactly.
Do king bed frames come with a headboard?
Many of the king beds in this collection include a headboard, especially upholstered and panel styles, while some platform frames are sold without one. Each product title and listing tells you whether a headboard is included. You can also add a separate king headboard to a frame you already own.
Does a king bed need a center support?
Yes, most king frames need extra support down the middle because the mattress is so wide. Platform beds usually build this in with slats and center legs. If you are using a basic frame, check that it has a center rail and support feet to prevent sagging over time.
