We've owned this set for a year and our daughter still loves it. She was crawling when we purchased it and now she's walking and still plays with it. We've now added piklers and wooden slides. We're able to switch up her play area pretty quickly and use for different purposes such as stacking, dollhouse, 4 tunnels, turn them upside down for great balancing, rolling a ball in them. They're loads of fun. We sit on them and they're pretty sturdy. When we first got them, we tried our best to recreate the configuration that's pictured and found out that it's boring to leave it like that as this should be open end and fun. This was a splurge for us that we don't regret.
