I saw this hot deal and would likely have bought it for myself if they would ship to Canada (or even accept my cc). Anyways, I have the Single of this stroller and love it. I know officially they are rated for 40 pounds each seat but I've read the manufacturer did testing on them too much higher. My almost 4 year old son doesn't ride in this stroller anymore (it's his little brothers) but I had him sit in it too see how comfy it would be for him. He is 34 pounds, 39 inches (turns 4 in May), so he is pretty lean and mean. His head is much higher than the backrest, I'd think if it's just for him to hop in and out of for rest breaks (or for a vacation somewhere) then it would be ok but if your kid likes to ride a long time it might not be too comfy for him. My single is great to load up (the handles) with lots of stuff, it's easy to fold and light enough, has a great sunshade and full recline seat (and is nice if you have long legs).
