Sleep is one of the most important pillars of our wellbeing. As we spend around 230,000 hours of our lives in this mostly unconscious state, it makes sense to ensure those hours are as restful as can be.

Having the right mattress on your bed for your height, shape and body could have a huge impact on the quality of your shut-eye, which leads to better health, more productive days and a happier life, too. Now, who wouldn’t want that?

Read on to find the right mattress for you, as well as deals and discounts should you wish to make a purchase.

Hybrid mattresses

A hybrid mattress is exactly what it sounds like. It’s a type of mattress that combines two or more support systems, typically an innerspring system with layers of memory foam or latex. Hybrid mattresses balance the pressure relief of a memory foam mattress with the classic feel of an innerspring mattress, and they’re often cooler for sleeping on than other models, too.

This type of mattress is best for heavier people as the coils can handle heavier weights and also provide the support needed for back sleeping and stomach sleeping.

Memory foam mattresses

A memory foam mattress is made from a polymer known as polyurethane. This material was actually created for NASA but has since become a staple in furniture and mattress construction. Memory foam generally has a soft feel that slowly compresses when pressure is applied. If you lie on a memory foam mattress, you should feel yourself slowly sink in. There are no springs in this mattress.

Memory foam mattresses are usually a good choice for those needing a bit of pressure relief due to back or joint injuries. They cushion the joints and relieve pressure on the heavier areas of the body. It also takes the shape of your body and fills in any gaps. This helps keep your spine in neutral alignment.

Pocket spring mattresses

One of the most luxurious mattresses out there, this type is made from individual, small springs housed in their own pocket of fabric. This means each spring moves independently, providing more support than an open spring mattress, for example. You can buy soft, medium or firm versions, depending on your preference.

This option is a good choice for couples, as the separate springs will cater for your different needs and weights, while also minimising the risk of you rolling towards your partner in the middle of the night.

Open spring mattresses

Also known as open coil or continuous coil mattresses, these babies contain one long piece of metal wire coiled into numerous springs. It’s a great value for money option and is often lighter than other models, making them easy to turn and manoeuvre.

If you’re on the hunt for a guest bedroom mattress or a child’s mattress, this could be the best option for you. They tend to be less supportive than other models and will often need to be replaced regularly – perfect for an ever-growing child.
