Delivery times for Republic of Ireland orders will be issued at the time of order.
Due to the increased global demand for PPE related products, we are currently experiencing some delays in the supply of quality raw materials we use in the manufacture of your Mammoth mattress. Your order and discount is in safe hands and we do anticipate this only being a short term challenge. We will continue to make every effort to achieve our estimated delivery times. However, this short term issue may on occasion result in the delivery of your Mammoth mattress to be extended by maybe one or two weeks.

Returns Information

If you would like to return a product, you can do so by informing us within 14 days of delivery. Due to the intimate nature of these products, all mattresses and pillows are exempt from the statutory cooling off period under the Distance Selling Regulations when they have been unsealed from their original packaging. Therefore, for reasons of health and hygiene, mattresses that have been unsealed from their original packaging will be deemed to have been used and cannot be returned for any reason other than a manufacturing fault.

Unless your item is faulty or you are returning due to an error on our part, you will need to pay the costs for the return. Please see our Terms of Sale for more details. If you would like to return an item from your order, please email us at to arrange collection.

Non-returnable products

Please note that due to hygiene reasons and the nature of their packing once delivered pillows and bedding will be deemed to have been used. As such, pillows & bedding items cannot be returned and are non-refundable.
