We bought this set up for our grandsons to sleep on when they visit.  It took about 2 1/2 hours to assemble and is sturdy.  The only issue we had was ordering a regular twin mattress for the trundle.  It is a little shallow and having a regular twin made it nearly impossible to open.  We bought a thinner mattress from IKEA and it works great for little guys who need to be close to the ground.  Very nice set!
