The Perch Nest stands about 42 tall, at least a foot shorter than a typical loft bed, making it a perfect first bunk that allows for goodnight kisses and an increased sense of security. While both of its orientations fit a twin mattress (or two), its full of possibilities:

• As a loft bed with ladder, children ages 6+ can sleep on the top bunk, with either a play space or a floor-level mattress below, and
  
• As a canopy bed, its perfectly cozy and can fit an optional add-on trundle bed.
  

Use a standard Twin-Size Mattress with a thickness not greater than 6″ (Do not use abox spring.)
