I just received the dining set and am very happy with it.  The table was easily assembled by one person (hubby) and it seems very sturdy. It accommodates 4 diners with no problem.
The chairs are super comfortable (no cushion needed) and all four chairs stack together - perfect for our small outdoor deck space. The chairs fit under the table so having a meal while seated at the table is very comfortable.
One chair arrived slightly damaged and Wayfair.ca has already ordered a new one to replace the damaged one.  Reporting the damage was one easy phone call and the Customer Service rep was a pleasure to deal with. Five stars for service @ Wayfair.ca
I hope the set is durable and can withstand the heat and wind of a southern Alberta summer.  Time will tell.
At this point, I'd high recommend this dining set.
