Our series of trundle beds are designed to last under a lifetime of repeated use, so your guests can sleep in comfort any time they come over. Made from strength-tested, tubular steel, our trundle beds use a welded wire deck for extra durability - and no squeaking or pinching springs! This twin size bed includes rollers so that it can hide under another bed (like our top deck trundle). The legs include stoppers to prevent sliding and fold out and lock in place to create a standing bunk that can be put together in minutes. Each deck holds up to 400 lb. No need for a box spring, just use a mattress. Product weights and Dimensions: 16" H x 39" W x 71. 5"D; 45 lbs.
