Well, one can argue about design. I like the "normal" roles better. But that's not the real problem. The roles are functional by far the worst we have ever bought. As already described by some other buyers, they have unfortunately really so stiff that the chair more drag over the floor as rolling - and not just when unoccupied chair, but also when you sit on them. Also the resulting noise does not really.
On insensitive floors (z. B. tiles) that is perhaps only unsightly, but without threatening to parquet floor mat scratches. I'll return these roles and probably order the "normal" hard floor casters of Topstar - in the hope that the roll instead of grinding.
