We bought this cradle for our new grandbaby and were so excited when the box came we put it together immediately. The instructions weren't as clear as they could have been. After getting it together, the bed is very sturdy and beautiful. The mattress is very thin and we will purchase a thicker one. Super bargain!!! We will add 2 more rocking blockers for a little extra stability, when not rocking. There are four holes so that won't be difficult.
