Herman Miller tip
Custom and made-to-order pieces (a huge share of what Herman Miller sells) can't be returned at all once ordered, so double-check dimensions and fabric swatches before you commit — this isn't a 'try it and send it back' kind of furniture purchase.
Sweet Zzz Mattress tip
You must sleep on the mattress at least 30 nights before you're allowed to start a return - trying to return in week one won't be accepted even if you already hate it.
