This is excellent!  We've had this in use for over a year now and haven't had any problems.  It looks really, really nice, and it is very sturdy.  It never shakes when I climb on the top bunk to make the bed.  Very good quality.  The trundle also is very easy to use.  We pull it out/push it in daily on a carpeted floor and it goes very smoothly.  Not difficult at all.  I would highly recommend this bunk bed and trundle!
