Metal twin size bed frame combines a headboard, side guardrails and a slatted 75 x 39 in platform to support a compatible twin mattress without a box spring. Six support legs and a heavy-duty metal structure work together to handle up to 485 lbs while helping reduce sagging. A 10.5-in high guardrail from the bed platform creates a barrier along the side to help prevent rolling off. With 12.5-in of clearance between the bed and floor, the open space underneath can hold bins, bags or extra bedding for organized storage.
