you can get the svan at Mothercare too, but it's about $1000 more expensive. No, I am not kidding, have asked Mothercare why, they said they cannot help it as that's officially how much they have to sell it for from UK pricing.
We have 2 svan chairs for our daughters 2.5 years and 9 months, and we think it's good. Have only tried the Tripp Trapp at Four Seasons hotel and there was no table accessory (may be available if you buy, I dunno), so unsure how it compares. But we found having a table at the front is invaluable when feeding under 2s. Having said that the Tripp Trap looks prettier.
