The 3-1 Nursery Center is very sturdy and larger than expected! To put in perspective its 34 lenght of the side of my queen bed. Space for the play pen when they get older is great and the adjustments for height for the bed is good. Few things where the velcro goes thru to secure the padding was sown shut so had to cut it to be able to set it in place and the music box is hard to place where instructions said to place but I was able to place it after.
