我的新Stokke® Tripp Trapp®成长椅在装完后不太稳，是不是我没装好？

Should the Stokke® Tripp Trapp® chair seem unstable after assembly, we ask you to proceed as follows: Loosen all screws slightly, make sure the chair is standing on a level surface, have an adult sit on the upper plate, and tighten the screws one by one – alternating between top left, bottom right and so on. The chair should now be stable. If this is not the case, please submit a claim with the retailer you purchased your Tripp Trapp® from, providing them with the serial number (which is located on the bottom of one of the siderunners) and both of the chair's legs, so that they can order a replacement pair for you.
