I am very pleased with these chairs.  Only ordered two just in case I didn't like them and it would be less of a hassle to return two than four.  But now, I will order 2 more.  They are very sturdy and quiet sliding on the floor due to the rubber tips on the legs.  I really debated whether to get the black or the yellow.  Went for it and ordered the yellow.  The pop of color is perfect.   

Pros: Very pleased.
Cons: no cons
