Sturdy.  Very cute but the bed had a very strong mildew smell.  I washed the fabric pieces thinking that was the problem- it was not and the plastic on the fabric melted a bit in the dryer.  We’ve had the bed about 3 months and the smell is less but still noticeable.  Also the bottom fabric pieces are only held on by Velcro sticky tape.  Doesn’t work very well.  We ended up just removing the bottom fabric pieces for everyday use.  The canopy does make it hard to tuck in you little one as well so we removed that piece too.
