Why Choose a King Platform Bed?

A king platform bed is the ultimate upgrade when you want more room and a modern look. A Zinus king bed frame uses a strong platform bed frame design with built-in slats, so your Zinus mattress or memory foam mattress doesn’t need a box spring. Whether you prefer a wood style or a sleek metal bed frame, a Zinus bed frame keeps your space feeling luxurious, not bulky.

King Size Fit Guide

In most bed sizes charts, the king is the widest standard option at 76" × 80". Choose a king bed frame if you share your bed, have pets or kids who climb in, or simply like extra space to stretch. For bedrooms around 12' × 12' or larger, a Zinus platform bed creates a comfortable, supportive setup that fits your lifestyle.
