One of the two chairs is about to fall apart.  screws and bolts/caps came loose already.  These are not our primary outdoor chaise chairs and have been sat in less than 40 times.  We keep them inside when we are not sitting in them.  Very poor quality.  
I would not suggest for an older person or someone who has poor balance.  One needs to be careful when sitting down.  We've been fine.  The only good thing is that they are comfortable.  However, no longer safe.
