The belt is an inexpensive and well-functioning solution for securing our small Klettermaxes (11Monate, about 10kg) in our Stokke Tripp Trapp. The belt was easy to install and adjust to the size of our son. A star deduction there, because the metal grommets for adjusting the strap length is easily sharp (but not so much that I would have concerns apply the strap) and because I have to again make a little tighter the belt every 3-4 days because he somewhat with time locktert.
