Cocoon by Sealy tip
You have to sleep on the mattress for at least 30 nights before you're allowed to return it — your body needs time to adjust, so don't bother requesting a return in week one even if it feels off.
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.
