Best Dunelm mattress toppers

“At Dunelm the label on the bag matters less than what is inside it, since Dorma and Fogarty are Dunelm brands too. Choose memory foam if your shoulders and hips need relief, and a washable fibre topper if you mainly want a softer, cleaner bed.”

Memory foam or fibre

The filling matters more than the brand label. Memory foam moulds to the shoulders and hips and spreads pressure, which suits side sleepers on a firm mattress. Polyester fibre makes a bed softer and springier for less money, which is the job the fibre toppers here do at the lowest prices, but it compresses where you lie.

How deep a Dunelm topper should be

Depth, from 3cm to 10cm at Dunelm, sets how much the bed changes. A 3cm fibre layer such as the Fogarty Quick Dry freshens a mattress you already like. Between 5cm and 6.5cm a topper softens a firm mattress noticeably, and the 10cm Gel Fusion or Dorma TENCEL Blend is the one to consider if your shoulder or hip still presses through. Deeper foam also weighs more, so a 10cm topper is harder to lift and fit. A topper also adds its full depth, so check that your fitted sheets are deep enough.

Washing, allergies and cooling

Care is where Dunelm toppers differ most. Only the Rebound and Fogarty Quick Dry can be machine washed and tumble dried whole. The Gel Fusion, Dunelm Memory Foam and Fogarty Memory Foam have machine-washable covers, and the Dorma TENCEL Blend and Full Forever are sponge or spot clean only. Allergy UK’s house dust mite factsheet states that “Washing at 60 degrees centigrade or above will kill mites”, and the NHS advice on allergic rhinitis is to use synthetic bedding and wash it regularly at 60C and above. No Dunelm page ranked here gives a 60°C wash temperature, and Dunelm claims the Dorma Anti-Allergy protects against bacteria and bedbugs but makes no dust mite claim, so allergy sufferers should put a mattress protector that washes at 60°C over any of them. For heat, the Gel Fusion is the only foam topper here with gel and ventilation holes, and Ideal Home’s reviewer, who slept on a 6cm double for two weeks in a very hot spell of 25-degree days, reported that she “didn’t wake up sweating or clammy”.

Dorma, Fogarty or Dunelm

All three labels belong to the same retailer. Dunelm states that Dorma was established in 1921, has held a Royal Warrant since 1961 and was acquired by Dunelm in 2008, and Furniture News reported in October 2015 that Dunelm had bought the rights to Fogarty, a bedding brand with almost 200 years of history. The label does not predict price, but the guarantee differs. Dunelm’s toppers and protectors guarantee list gives the Dorma TENCEL Blend 10 years and the Dunelm Memory Foam topper five years, although that topper’s own product page says two years, and the other six pages state none.

Returns, and when a topper is the wrong buy

Dunelm offers no sleep trial on its toppers. Its returns policy allows change-of-mind returns within 28 days, but for health and hygiene reasons mattress toppers qualify only if they come back sealed and unopened in their original packaging. A faulty item is replaced or refunded within 30 days of purchase or delivery. No topper fixes a worn mattress either, so if yours sags or has softened a lot, a new mattress is the better spend.

Dunelm toppers we left out

The Dunelm Cooler Than Memory Foam is, despite its name, a 4.5cm polyester fibre topper (£90 in a double), and at 3.7 out of 5 from 289 reviews it is the lowest-rated Dunelm topper with over 100 reviews. The Dorma Sumptuous Soft, 7cm of fibre in cotton, costs £110 in a double, £10 more than the 6cm Full Forever, and rates 4.4 from 250 reviews.
