These daycare cots are designed with care to ensure a comfortable napping surface for preschoolers and sleepy toddlers, making them great for classrooms, daycare centers, or any room in your home. The copolymer corners on each cot nest together tightly to allow you to neatly stack them up to 24 high for compact storage after nap time, and rolling casters (sold separately) can be attached to the bottom of the cots to simplify set up and clean up. The durable, non-flammable mesh fabric with a vinyl coating makes clean-ups a breeze - simply scrub the cot with a damp soapy sponge and wipe it dry. Constructed with a sturdy 18-gauge steel frame, these naptime cots withstand years of heavy-duty use.
