I had a triple set. A spacious carrycot on sprung wheels was a dream. It's not foldable or light. That's a given. But if you live in a house or condo with a lift and don't plan on loading it 5 times a day into the car, it doesn't matter.
It can handle deep snow, bad surfaces - it won't shake the carrycot and the baby inside even on harsh terrain. We have used it many times as a travel cot. We enjoyed it while the little one was lying only. When he didn't want to be in the carrycot anymore, we switched to an urban, foldable and handy pushchair.
But for the first months it's a real experience to stroll with it. And everyone praised it. Strange people, just like that. At least one person a day always 😍 And it will last you even 5 kids, I would say. If not yours, you'll pass it on. It's a solid metal chassis, without any fancy systems. There's nothing to go wrong. I really loved it.
