In non-promo periods, you can simply copy your code and paste into the box at the checkout to redeem.

During promotional periods, you may not need a code to enjoy Simba mattress offers. They will be automatically applied at the checkout. Please note students, key workers and others verified via GoCertify will receive a higher discount during this time, and you’ll need to apply it to your basket in the same way you’d redeem your code in non-promotional periods.

You can only apply one Simba promotional code per transaction, and you won’t be able to apply a code on top of any existing discounts during promotional periods. During Giveaway periods, any Simba mattress discount code added will result in no free items, although savings will continue to apply. For example, if you have a student discount code and are ordering a mattress during a Giveaway, your items will no longer be free, but you will get the flat discount on all relevant products.

Many of our offers are category-specific, meaning the same offer might not necessarily apply to other products. For example, Simba mattress deals may differ from pillow or bed offers. Those who are students, key workers and others verified via GoCertify can enjoy a flat discount – but you won’t be able to use your code on our Refurbished range.

No matter what you buy and when, you’ll always get fast, free delivery and returns; new mattresses all include an exclusive 200-night trial, 10-year guarantee and 0% finance options – and you won’t need a Simba sleep discount code to enjoy them.

If you’ve tried to redeem your Simba coupon code at the checkout and your discount isn’t showing, you can reach out to us at help@simbasleep.com and we’ll do what we can to help.
