For over 60 years, Rize’s Insta-Lock bed frame series has provided unmatched security and stability for box springs and mattresses. The Insta-Lock design provides the box spring with a secure and stable fit. Choose from two options: a frame with glides or a frame with 4 casters and one glide. Both frames adjust to fit Twin, Full, or Queen box springs and mattresses, and include a center cross rail for added support. The headboard brackets on the frames are made to attach to bolt-on headboards. Because no tools are needed for assembly, setup is quick and easy.
