Wesley Allen trundle beds are an ideal solution to adding sleeping capacity while conserving space. A Wesley Allen bed with trundle stores the trundle underneath the bed when not needed. Wesley Allen pop-up trundle beds lift up so the trundle mattress is the same height as the bed. A Wesley Allen twin trundle bed when used in conjunction with another twin bed, creates a king size bed. Constructed from iron, there is a choice of a Wesley Allen twin trundle bed or a Wesley Allen full trundle bed.
