Settling on your perfect mattress

Before you purchase your new Silentnight mattress, it's important to consider which mattress is the best fit for your bedroom. For anyone who sleeps alone or whose room is restricted by space, our Silentnight single mattress collection is ideal. Alternatively, a Silentnight double mattress could be the perfect fit. If it's a spacious sleeping solution you're on the lookout for, you'll be sure to love our Silentnight king size mattress collection.

Silentnight produces a range of beds that suit different budgets and sleep preferences, so you can find the right option. All our Silentnight mattresses feature brilliant properties developed to the highest standards. With such a variety on offer, you can see why Silentnight is the UK's most trusted sleep brand. We're immensely proud to showcase their collections, so shop by type below to find the one that's right for you.

Silentnight Mirapocket mattress: pocket sprung

Silentnight has created its innovative spring system that provides zoned support and a fantastic night's sleep. Their Mirapocket springs are scientifically proven to promote healthy spinal alignment and posture. Like pocket springs, each spring is encased in its own pocket of fabric, and they move individually, allowing the mattress to move to the contours of your body. Silentnight miracoil mattresses are particularly beneficial for anyone sharing a bed; these springs are recognised for their motion isolation properties meaning that any movements your partner makes throughout the night will be restricted to your partner's side of the bed, allowing for an undisturbed night's sleep. Often paired with other materials and comfort layers, pocket springs supporting Geltex layers and foam options will be explored below.

Silentnight Miracoil mattress: open coil

Similar to open coil mattresses, Silentnight's sleep experts have gone above and beyond to create a spring system that provides edge-to-edge, zoned support to improve spinal alignment. More durable than a standard open coil mattress, there's also less motion transfer, so you aren't disturbed by your partner as you sleep. Often cheaper and providing firmer support than other mattress types, the Miracoil makes for a great option when on a budget.

Memory foam and other foams

For all those sink-in snoozers, you're sure to love Silentnight's memory foam mattress range. A foam layer is often accompanied by a pocket sprung or open coil spring unit; however, Silentnight features a range of mattresses that combine multiple layers of reflex and memory foam to create an entire foam mattress too. Memory foam is made of millions of tiny holes that seep out air when pressure is applied, contributing to the body-moulding and heat retention properties that this material upholds. Therefore, if you're a hot sleeper, opt for a bed that utilises Geltex instead of Silentnight's foam options.


For hot sleepers, Silentnight mattresses incorporating Geltex help you maintain a comfortable sleeping temperature throughout the night. Comprised of a gel-infused comfort layer often paired with a Miracoil or pocket sprung unit, the elasticity provides a body-moulding yet breathable mattress surface. Maintain a comfortable body temperature all night long with one of the Geltex Silentnight beds.

Eco-friendly and technologically driven initiatives

Silentnight has recently put sustainable products at the forefront of its operations, showcasing an eco range of mattresses that incorporate recycled fibres into their sleeping solutions. 90% of the waste produced their sites in northern England and have joined initiatives to significantly reduce their carbon footprint. Moreover, Silentnight is a carbon-neutral business offsetting more carbon than they produce in their manufacturing processes.

What's the right mattress support for me?

It's easy to feel overwhelmed when browsing for a new mattress. How do you know what mattress support tension is correct for you? It all depends on your preferred sleeping position. Silentnight has a support tension so everyone can get their ultimate night's sleep. Shop by comfort or support type using the filters above.

"I prefer to sleep on my side"

When you sleep on your side, your shoulders and hips need extra cushioning to promote healthy spinal alignment and get the best night's sleep. This is why a soft or medium support tension mattress is best suited for this sleeping position.

"Back or stomach sleeping is my go-to"

Conversely, sleeping on your back or front requires firmness ratings from firmer to extra firm. This is so your spine is aligned in a healthy position all night long. Extra firm tensions are best designed for anyone who needs additional firm support due to back or joint pain. You can find the option from the UK's most trusted sleep brand. If it's a firm or extra-firm mattress you're looking for, you can count on the UK's most trusted sleep brand.

"I sleep in all positions"

Neither too soft nor too firm to support you whilst sleeping on your back, front or side, medium firm support is the best choice for anyone who sleeps in all positions. You can find a range of medium-firm mattresses with exceptional quality from Silentnight. What's fantastic about our medium firm range is that regardless of how many times you change position during the night, you can expect soothing pressure relief at all times.
