Interior Define tip
The processing fee jumps from 15% to 50% the moment upholstery — a sofa or chair — is involved instead of a stocked accent piece, so factor that steep fee into any custom sofa order before you buy, not after.
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.
