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.
Serta tip
This trial is capped at one return or exchange per household every 12 months, so if you're testing more than one mattress model for a household, you can't return them all.
