Our take on the I-34G Twin/Full

The Mantua I-34G is a steel bed frame that adjusts to fit Twin and Full beds. Its Insta-Lock design holds the box spring securely, and it assembles without tools. Four legs with glides protect the floor and keep the bed from sliding. It suits anyone replacing a worn frame or setting up a guest or kids' room on a budget, and it competes with other steel frames on simple, tool-free setup rather than on style or storage.
