This bed comes in 4 big pieces that are made of hard plastic, that is very durable. When putting the bed together, two of the 4 pieces didn't match up perfectly, which made it difficult to get the bed put together properly. We had to use a chisel to get one of the pieces to fit.
After put together, it looks great. This is our second little tikes bed. We bought a twin sized one for our other child two years ago. We had same issues putting the first one together too....It may take two people to hold the pieces just right to get them to snap together, but otherwise a great bed for a great value!!
