Target age: 5 months to about 3 and a half years old Size (when unfolded) Approximately W126 x D126 x H70cm (when folded) Approximately W26 x D26 x H70cm Weight: 4.3kg Materials: Aluminum, polyester, polypropylene, TPR Includes: Main unit, 4 stability plates, storage bag (new and unused) * Please note that the storage belt is not included. I used it with a futon inside on top of a mat during sleep, so I don't think there are any stains. I washed it again at the end of the year. I also wiped the legs with disinfectant wipes. At that time, I noticed that one of the rubber bottoms of the safety plates was slightly yellowed. I don't remember staining it, but please understand. I took pictures because I thought I might forget how to assemble it. I will also include them, so please refer to them if you like. I have stored it in a box (I haven't touched it since I bought it) in a place away from direct sunlight, but please understand that it is stored by an amateur.
