We just received this set, and while it is deep seating, it is smaller than it looks online.  I didn't look at the dimensions, which was OK because I wanted a small set.  It seems to be good quality.  We'll see after we've used it for a while (with 4 kids and 2 dogs).  The only negative I have (and why I didn't give it 5 stars) is that the cushions are very slippery and don't stay put.  I will have to use velcro underneath the seat cushions to get them to stick to the chairs.  

Pros: They provide hooks so you can hook all 5 units together into a sectional that doesn't slide apart.
Cons: The cushions are very slippery and slide off the units constantly
