What’s The Difference Between Open Coil And Miracoil Mattresses?

Similar but not the same, open coil and Miracoil mattresses are both great options for anyone on a budget or looking for a sleeping solution that provides more orthopaedic support. Here are the main differences between these two mattress types:

Open coil mattresses

  • The most popular kind of open coil mattress is gauge and Bonnell springs, essentially consisting of a continuous wire that forms the entire spring unit in the mattress.
  • The ‘gauge’ can change and this refers to the thickness of the wire used for the springs. A 12 gauge unit provides firm support, often used in orthopaedic mattresses. If you want something a little softer, 13.5 gauge can provide support but with a less rigid tension.
  • Much lighter and cheaper to make than pocket sprung mattresses, open coil mattresses are great for budget options.
  • One disadvantage of open coil mattresses is that they can eventually ‘roll-together’. After years of usage, the middle of the mattress can begin to sag and for those who share a bed with their partner, this may feel like you’re literally rolling together. Because the open coil mattress is made from one continuous spring, you will also be able to feel your partner move around in the night.

Miracoil mattresses

  • Designed exclusively by Silentnight, Miracoil mattresses are very similar to open coil options. However, the disadvantages stated above is exactly what Silentnight wanted to target.
  • The continuous spring is ‘knitted’ together with a series of interwoven springs, although these are linked vertically rather than horizontally, like most open coil spring systems. This ensures less partner disturbance too.
  • Overall, such a spring system provides firmer and zoned support, similar to Silentnight’s Mirapocket system. The upper and lower ends of the bed offer softer support for comfort in those areas of your body. The middle portion of the bed targets your back and torso to provide zoned firmer support, helping achieve healthy spine alignment.

Overall, Silentnight’s Miracoil system aims to build upon the common woes of open coil mattresses. The choice essentially comes down to budget, however, if you want to further delve into what’s the perfect mattress for you, read ‘What is the most comfortable mattress?‘.
