I used to know some of the Cybex people (it was a European company), and they congratulated us on beating their best safety scores at the time. Now Cybex is owned by an Asian conglomerate (Goodbaby).
The Kioma difference in materials quality and performance is both quantifiable and qualitative. We have to charge a price that covers our work in design and production costs. But I completely get it if the Kioma seat is too expensive for your preferences.
As a side note, if you want to be blown away by prices check out the $10,000 cribs (https://nurseryworks.net/collections/cribs/products/gradient...), $1000 bassinets (https://www.happiestbaby.com/), and $5000 strollers (https://silvercrossus.com/category/strollers/).
Thanks for the feedback!
