Simba Sleep discount code

Free contact-free delivery at Simba

Mattresses can get pricey, so the free weekday delivery is a great perk when shopping at Simba Sleep. You can pick the date of your choice at the checkout. Alternatively, weekend delivery and specified time slots cost £20. Next day delivery costs £40. All delivery is contact-free. For orders that don’t include mattresses, standard delivery is free and takes 2 to 5 working days. Check the delivery information for any updates.

Simba's returns policy

Simba is so confident you will love your mattress that it offers a 100-night risk-free trial, allowing you to buy with peace of mind. Any Simba product that is not a mattress can be returned in the same condition and in its original packaging within 14 days of receipt.

Cancelling a Simba order

If you need to cancel your Simba order, the best course of action is to contact the customer service team as soon as possible so they can prevent the order from shipping and process your refund.
