We have two Stokke chairs with the straps useful for toddlers. The chairs have been great for our kids from ages 2-12. They are fully adjustable, easy to clean and save your normal chairs while the kids grow.
Details on these chairs can be found here ($350 each new including taxes). We are asking $175 per chair or $325 for two (FIRM).
