30-day returns.
If it's not quite right, you can request a return within 30 days of delivery, and Snugfield will email you return instructions. Change-of-mind returns must be unused, unassembled, and in their original packaging. There is no restocking fee. Depending on the item's packaged size and weight and how it needs to be collected, a change-of-mind return may have a return shipping or pickup cost. We only deduct the actual cost: we tell you the exact amount and get your OK before arranging a paid return, and if there is no cost, nothing is deducted. Returns for damaged, defective, or incorrect items are free.
