What is a mattress topper?

A mattress topper makes a bed more comfortable. It serves as an extension to the mattress, providing it with extra cushioning and support. Some toppers are softer than others, while others offer more support. If your existing mattress needs a pick-me-up, a mattress topper can give it a new lease of life.

Benefits of using a mattress topper

A mattress topper adds an extra layer of cushioning to a bed that’s lost its plumpness. If your mattress suffers from being too firm, it can soften the sleeping surface considerably. A mattress topper can also extend the life of your mattress, making it a cost-effective alternative to buying a brand new one.

Types of mattress topper

Memory foam

Memory foam toppers feel luxurious to sleep on. They mould around your body shape and relieve pressure on your joints. A high-density memory foam topper tends to be more durable and provide more support than a low-density one.

Feather fillings

These toppers are filled with feathers, which gives them a fuller feel. They provide natural warmth and insulation, making them ideal for colder, winter months. Feather-filled toppers are also exceptionally soft and hold their shape well.

Synthetic toppers

If you suffer from allergies, you may want to consider a synthetic mattress topper. Made from either hollowfibre or microfibre, these toppers vary in thickness. Hollowfibre toppers are more supportive, while microfibre toppers have a softer feel.

How thick should a mattress topper be?

The thickness of topper you need depends on the age, feel and condition of your mattress. The thickest mattress toppers, up to 4 inches, are best for rejuvenating tired, old mattresses. Toppers of up to 3 inches thick offer a good level of comfort and support. If your mattress is relatively new, a thinner topper of around 2 inches can give it a more luxurious feel.

What size mattress topper do I need?

Mattress toppers come in a variety of sizes. They can be as small as 90cm x 190cm or as large as 180cm x 200cm. It’s important to get a topper that matches the size of your existing mattress, because, unlike duvets, they can’t scale up.

Fitting a mattress topper

Securing a mattress topper to a bed is easy. Typically, it’ll be held in place with either 4 elasticated corner straps or an elasticated skirt which stretches over the sides of the mattress like a fitted sheet. Once in place, the topper stays fixed to the mattress, preventing it from bunching up or coming untucked.

Maintaining a mattress topper

Cleaning your mattress topper regularly will keep it free of harmful allergens and bacteria. Ideally, it’s best to clean the topper at the same time as your bed sheets. Most mattress toppers can be washed in a washing machine, but not all of them, so it’s best to check the instructions carefully before you clean them.

The difference between a mattress topper and mattress protector

A mattress protector keeps the mattress clean and hygienic. Some mattress protectors are waterproof, while others act as a barrier to allergens and irritants like dust mites, pet dander, bed bugs, stains and sweat. Unlike toppers, mattress protectors offer little cushioning or support. Mattress protectors and toppers can be used on their own or together with the protector placed over the topper.
