Return Policy

We know a weighted blanket can be a big commitment and a good night's sleep is so important. That’s why we offer all our customers a 100 Night Sleep Trial.

How does the 100 Night Trial work?

It’s simple! Place your order on our site. When your weighted blanket is delivered, unbox and get ready for the best night’s sleep, risk-free. We recommend using it for a minimum of 30 days, as it can take time for your body to fully adjust.


We’re sorry to hear you might be returning your Sumo Weighted Blanket. Our sleep-trial policy lasts 100 nights, during which if you are unsatisfied with you purchase you are eligible for a return and full-refund. If 100 days have gone by since your delivery, unfortunately we can’t offer you a refund.

Simply send an email to and we will coordinate your return for you.

Once your return is received, we will send you an email to notify you that we have received your returned item. We will also notify you of the approval or rejection of your refund. 

Note: The blanket must be clean and free of any debris or pet hair. Items must be returned in their original bag - and undamaged, just like you received them. Sumo Sleep reserves the right to apply a 40% fee to blankets that are returned in poor condition.

If you are approved, then your refund will be processed, and a credit will automatically be applied to your credit card or original method of payment, within a certain amount of days.

You will be responsible for paying for your own shipping costs for returning your item. Shipping costs are non-refundable.

If you are shipping an item over £75, you should consider using a trackable shipping service or purchasing shipping insurance. We don’t guarantee that we will receive your returned item.

Exchanges (if applicable)

We only replace items if they are defective or damaged. If you need to exchange it for the same item, send us an email at and we will coordinate your exchange. If an item has been exchanged for another weight or colour we can no longer honour the 100 night trial.
