I can't comment on other locations as the etobicoke one has been my primary since I moved out on my own. A couple points I've noticed about my many trips there.
1) Approaching parking from the rear of the building will save you some time, there's access from a side road off Evans that will get you to the underground parking quickly. It's much easier to exit as well if you try to shop on a Saturday afternoon.
2) If you have multi boxes for your pieces, make sure both are the same color. I bought a desk that came in 2 boxes that was in the same location, brought them home only to find out the top shelves were the wrong color. Trying to exchange them turned into the longest exchange of my life. They sent an employee to get me a new box, after 20 mins of waiting I decided to get it myself. I found said employee wandering around looking for it, when I asked why he couldn't find it, he said this was his first time working the stacks. Ridiculous.
3) There's a labelled shortcut beside the children's play area that lets you skip the showroom and puts you right at the beginning of the self serve kitchen area. If you walk straight through this area, there's a break in the wall on the left that puts you beside the flat buggies for the stacks.
I have no issues with the furniture itself, they're good interim pieces but chips if you look at it the wrong way. Pretty good pricing on the LED accent lighting too, although you have to pick it up after you pay now since they pulled it from their shelves in lighting.
