New England Woodcraft Bunk Beds feature solid hardwood posts and rails and are available with wedge-lock, bolt-on or tool-less springs. Our E-Z Lock tool-less bed assembly exceeds the strength of our competition because steel pins are welded to a steel U channel so that the steel bracket forms a metal-to-metal wedge-lock between the pin and back. Beds can be assembled and disassembled repeatedly over generations of use. No tools are required for assembling or disassembling the bed. All Bunk Beds have passed Federal Government Performance Test requirements.
