These seem to fold up nicely.  We have a small living with a few pieces of very large furniture, but occasionally we need a place for someone to sit and watch TV with us...we always eat watching the TV (ignoring our lovely brand-new dining table, also from Wayfair) ...I need one of them in a small bedroom so I can use it for a study table.

Pros: Price was right.  Fits our needs perfectly.
Cons: None.
