Quick summary: Sleep on it normally—that is what the trial is for. Marks and stains from normal use do not affect your refund. Return the mattress or accessory undamaged and send your request by email within 100 nights of delivery. No paperwork needed, and no partial refunds apply.

We offer 100% refund if you are not happy with your purchase within 100 Nights from the date the mattress/accessory was delivered to you.

Return conditions: what's fair and what's not

We want this to be a fair deal and do not want the trial to be misused. To be clear about what that means: normal use, and stains that result from normal use, do not affect your refund. You do not need to keep the mattress unused, wrapped, or in its original packaging—sleeping on it properly is the whole point of the trial. The exception is extreme damage or misuse: heavy soiling, tearing, or tampering with the product in any form. In those cases we are unable to accept the product back.

No invoice needed

You do not need to produce the original invoice to claim a refund under the 100 Nights Trial. Your order number is enough—and if you do not have it to hand, the email address or the mobile number you used when ordering will let us find it.

The deal is simple

If you do not like the product, please give the product back in undamaged condition and we will refund 100% of the amount. Please note that there are no partial refunds under any circumstances. We either give a 100% refund or no refund at all (in case the mattress/accessory is damaged or tampered with). Hope this is a fair ask!

To be eligible for a refund, make sure you:

  • Use the mattress/accessory normally – marks and stains from normal use are fine; heavy soiling or damage is not
  • Send your refund request to hello@sundayrest.com within 100 Nights of delivery, quoting your order number, or the email address or mobile number you used when ordering
