It is extremely unlikely that a European king size mattress will fit in your car and attempting to transport it in this manner could result in incorrect handling and damage to your mattress which can void your guarantee. We offer free mainland UK delivery on orders exceeding £100. Additional charges may apply for deliveries to remote areas or the Highlands, which you can ascertain by entering your postcode in the delivery section on each item or product page. For orders less than £100, a minimal fee, starting at £10, is applicable.
