Next Divan's guide to mattress filling

Most of us will spend around one third of our life lying on one, but have you ever thought about what’s inside your mattress? Well, Next Divan is here to explain.

Mattress filling explained

Mattresses essentially fall into two types: sprung and non-sprung or foam. However, that’s only half the story, as mattress filling can affect how well they perform, as well as how much they cost. Sprung mattresses come with various fillings which are selected based on their resilience, durability and capacity to absorb body moisture.

Non-sprung mattresses are generally manufactured from layers of foam with various densities in order to create different levels of comfort and support.

Mattresses, such as orthopaedic models, are often hybrids of both sprung and foam types.

What’s inside our mattresses?

We use both natural and synthetic materials for the mattress filling in our products. Polyester is a synthetic material which is used as a filling in almost all mattresses, thanks to its excellent recovery and cushioning properties. This filling comes in the form of polyester fibres which are used to construct a mattress-sized pad.

Mattress pads come in various weights and depths, but are sold according to a specific GSM (grams per square metre) value. The best-quality mattress filling is in the weight range of 800-1,200 GSM, whereas cheaper options are usually between 600 and 800 GSM.

Pads are often manufactured by combining polyester fibres with two different GSM values, which usually means that half of the pad is designed to be more supportive, while the other half is softer and therefore more comfortable.

Natural mattress fillings are also available such as wool and silk, which are more breathable and absorb more moisture than synthetic alternatives. Naturally fire-resistant and biodegradable, they also minimise the occurrence of mould and mildew. In addition, these types of filling will help to regulate your body temperature while sleeping, keeping you cool in the summer and warm in the winter.

Designed to hug the contours and curves of your body, foam mattresses offer highly personalised support and spine alignment. We use memory foam and reflex foam in our non-sprung and hybrid products.

Originally developed in 1966 by NASA, memory foam consists of temperature-sensitive polyurethane material, together with other ingredients to increase its viscosity and density. Reflex foam is another polyurethane foam offering medium firmness levels, which explains why it is often used for manufacturing orthopaedic mattresses.

As both of these foams are resistant to dust mites, they will provide you with a healthier sleeping environment. Moreover, if you purchase a foam-only mattress, there is also no need to turn it on a regular basis, unlike more traditional options.
