Overall the Stokke cushion is a disappointment.
We love the Stokke chair and baby set, both well made and worth the added expense compared to their competitors. On the other hand, the Tripp Trapp chair cushion is a bit of a disappointment. The cotton fabric seems cheap and (as noted on the Stokke site) is not stain or water resistant. The batting used for the cushioning is fairly thin, so I don't think that it really cushions all that well. Lastly, the instructions for putting on the back-rest part of the cushion was sorely lacking..after some frustration, I ended up going online and finding a youtube movie that demonstrates how to install it. If you are charging premium prices, the consumer expects a superb product.. which this is not. One positive was that it did fit the chair well.
Consprice for quality, fabric of poor quality, not stain/water resistant, not much cushioning, poor installation instructions
