Who Makes Dorma Mattress Toppers?

dorma bedding by dunelm

As one of the world’s leading brands in high quality bedlinen and soft furnishings, Dorma was bought out by Dunelm in a £5 million acquisition back in 2008.

Since then, Dunelm has owned the Dorma brand, and supplied their top-quality products via their UK-based department stores. 

Dorma’s range of stock at Dunelm is varied and focused on improving both the aesthetics and comfort level of the buyer’s bedroom.

Additional Info:

Dunelm offers standard free delivery on all orders above £49. If you need to get your mattress topper in hurry, you can pay an extra fee for express delivery or may want to consider collecting the item from one of their stores. Dunelm also has an easy returns policy, however the item should be in its original packaging and should not have been used. 

Sizes: The Dorma mattress toppers are sold in a wide range of sizes, including: single, small double, king, and super king. There are straps on each side so you can securely attach the topper to your mattress.

How to care for your Dorma mattress topper? Keep in mind that only the Dorma Full Forever Mattress Topper and Dorma Full Forever Anti Allergy Mattress Topper can be machine washed and tumble dried on low head. The rest should be spot cleaned with damp cloth. 

You may want to add a deep mattress protector, that will cover both the topper and your mattress. Try to find a waterproof one, which will protect your topper and mattress against any spills and accidental stains. It will also prolong their life and protect against allergens.
