1000 Mirapocket® springs are individually encased in fabric pockets, helping them to respond to your weight and movements independently for greater targeted support.
Mirapocket® springs are zoned in the center third to give firmer support to your spine, lower back, and hips, promoting better alignment and reducing aches.
Individually pocketed springs isolate movement across the mattress so you can sleep undisturbed when sharing the bed with a restless sleeper.
Stay cooler and comfortable with Eco Comfort Fibres™. They increase airflow through the mattress, drawing heat and moisture away from your body.
Sleep in comfort with Eco Comfort Fibres™ crafted from recycled materials that are kinder to our planet.

1000 Mirapocket™ springs unique to Silentnight, create a responsive mattress core that is personalised to your movements. Zoned in the centre third, the spring unit offers firmer support to your back and hips to encourage deep, spinal aligning support.
A layer of durable polyester helps to evenly distribute weight and pressure from the spring system for even support and greater mattress longevity.
The cover material is stitched to the comfort fillings to create a plush, cosy sleep surface.
Crafted from recycled materials, this layer increases airflow to reduce a build up of heat and moisture for comfort that is kinder to you and the environment.


Soft to touch knitted cover offers a cosy sleep surface.

Try this mattress at home for 60 nights with our free Comfort Trial. If it's not quite right, you can exchange it easily.
When does the trial start? - Your 60-night Comfort Trial starts the day your new mattress arrives.
What do you need to do? - Sleep on your new mattress for at least 30 nights, using a mattress protector. This gives your body time to adjust and allows the mattress to settle.
How do you exchange? - After 30 nights, if it's not quite right, simply get in touch to exchange it for another mattress of the same size - we'll collect your old one when we deliver the new.
Want to upgrade? Simply pay the difference.
If you choose a lower-priced option, the original cost will stay the same.
