Thank you for viewing. STOKKE Tripp Trapp Harness Chair Belt This is an older model harness. It has been home cleaned, but there may be some small stains remaining. There is no box or instruction manual, and everything in the photos is included. It came with a used Tripp Trapp chair I obtained. There's a part I haven't seen before, and it seems it was directly fixed to the back of the chair with screws because there were holes in it. It seems it was purchased from STOKKE in America a long time ago, so it has fewer straps than the Japanese version, and the seatbelt seems to be able to be fixed to a dedicated seat (I've included a reference image I borrowed). I don't know the details of how to install it, so I won't be able to answer any questions, so I'm selling it at a low price. Please purchase at your own risk (I don't have a baby, so I don't know how to use it at all). It will be sent by anonymous Mercari delivery with simple packaging.
