Support Systems Guide

What is a mattress support system?

The mattress support system is a vital component that makes up the core of the mattress and is key to support, comfort and sleep quality.

Silentnight's sprung mattresses feature either a Miracoil or Mirapocket support system and offer zoned support for better spinal alignment.

The secret to better posture has been revealed

The secret to better posture has been revealed

A third of adults suffer from lower back pain. To combat this all of our mattresses are zoned to add extra support to the hips and shoulders, which promotes healthy spinal alignment and back posture.

We teamed up with the University of Central Lancashire to put our zoned mattresses to the test. Studies revealed that our zoned mattresses beat non-zoned mattresses hands-down to scientifically prove they're better at supporting your spine in key areas around the lower back and pelvis.

Miracoil support system

Miracoil support system

Silentnight's Miracoil spring system offers outstanding support, superior spinal alignment, maximises sleeping space and reduces "roll-together" for less partner disturbance - making it ideal for couples.

This open coil spring system features a continuous length of wire 'knitted' into a series of interwoven springs, which are - unlike most open coil systems - linked vertically rather than horizontally to offer firmer support for you and your partner.

The benefits of Miracoil:

  • Zoned support for perfect spinal alignment
  • Designed to offer firmer support
  • No roll-together for less partner disturbance

Mirapocket support system

Mirapocket support system

Each mattress with our Mirapocket spring unit contains individual small springs housed in their own separate fabric pockets which respond independently to each other. Each spring helps to spread your weight evenly across the bed providing the perfect support and comfort that's second to none.

The benefits of Mirapocket

  • Pocket springs which conform and adjust to body weight for luxurious comfort
  • Individual responsive springs to provide tailored support
  • Edge to edge springs for maximum sleep space
  • Scientifically proven to improve spinal alignment and posture

*Listed spring counts are based on a king size mattress (measuring 5ft x 6ft 6in /150cm x 200cm). The amount of springs will alter on a pro-rata basis dependent on mattress size.

60 night comfort exchange

Our comfort exchange gives you 60 nights to get really comfortable before making a decision. If you're still not loving your new mattress within 60 nights from delivery, you can exchange it for another mattress. It's as simple as that.

Here's how it works:

  1. Pick your new mattress on the official Silentnight website
  2. Sleep on it for at least 28 nights as it can take a little time to adjust to a new mattress
  3. If you're not happy after the initial 28 nights you can exchange it for a new mattress, as long as you claim within 60 nights of delivery
