Choosing a mattress can feel like a minefield. Do you require pressure relief? Would proper cooling technology benefit you? Are you better suited to a firmer mattress as a back sleeper? All of these questions can make it feel overwhelming, especially with several certifications out there.
But at Silentnight, we know that the checklist runs further than comfort. You want safety, longevity and tailored support. That’s why we’ve put together this handy guide for our mattress ranges, giving you the answers before you find your perfect match for quality sleep.
Mattress certifications are what defines a mattress’ features, whether that’s breathability or movement isolation. They also protect your health and signal smart environmental choices, so they’re pretty important. Let’s take a look at our certifications to see which stand out to you.
Comfort Breathe™: Hot sleeper? Comfort Breathe™ is ideal for those who overheat during the night. With 15x more breathable foam compared to traditional foams, air flows freely through the mattress, leaving you feeling fresh all night long.
UltraGel™: Using a gel-infused comfort layer, UltraGel™ offers next-level pressure relief and comfort. Supporting you as you lay down, and then naturally bouncing back so you can move around freely without disruption to you or your partner.
Memory Cool™: Infused with graphite, Memory Cool™ forms around your body perfectly, relieving pressure and absorbing energy. It also takes heat away from your body, creating a sleep space 15% cooler than if you slept on standard memory foam.
Air Mesh™: Designed to enhance airflow, creating a more breathable and fresher sleep space through an innovative 3D honeycomb design. Air flows with ease around your body as you naturally move, encouraging that air circulation.
Miracoil®: A unique, supportive spring system that uses continuous wire wound into twice as many springs compared to standard coil mattresses. This achieves exceptional edge-to-edge support, targeted at the middle of your body while keeping your head and legs in softer zones.
Mirapocket®: Our own take on pocket spring, but with each spring working independently to minimise movement as you toss and turn during the night, so you can enjoy uninterrupted, restful sleep.
To make sure you’re shopping for quality that’ll last, here’s what to look out for when purchasing a mattress to suit your needs:
Always check product information, which will detail any mattress specifications and advanced materials such as Air Mesh™, so you know it’s ticking your every box
Opt for reputable brands with long-standing trust and transparent guarantees
While certifications are just a badge, they could determine how you rest for the next 7 years, so by researching into them, you can make a choice that’s personal to you
When you shop with us, you’re given 75 years of trusted expertise, so you know you’re in the best hands for a quality slumber. Plus, with a 60-night comfort exchange guarantee, you’re even given extra peace of mind as you make a decision that can transform your rest.
