After several cheap items from discounter we have "invested" in a super booster seat. The EOS is much more stable and better padded than cheap offers, the padding and the high-quality base properly fixed (no styrofoam, which merges with the time in breadcrumbs). The arms, under which passes the belt are drawn far enough forward so that the belt also underneath stays where it belongs. Conclusion: Finally a good stable and safe booster seat that also looks classy.
