Medium Soft Mattresses - Customised Comfort for Restorative Sleep

Choose from a wide range of fillings including:

Natural - Natural fillings come in a variety of forms, but the most common ones for comfort layering include cotton, silk, wool, mohair, hemp, and cashmere. These kinds of fibres have opulent softness and inherent ability to regulate temperature.

Latex - Resistant to mould, mildew, and dust mites, latex is a naturally occurring substance. It also relieves pressure points.

Memory foam - When you sink into the comfort layer, memory foam is what provides you with that calming, cocooned feeling. For pressure alleviation, it conforms to the curves of your body.

Gel - Choose Gel mattresses for a soothing, sink-in sensation and cooling effect.

Select from a variety of spring types, including traditional springs and pocket springs to find the ideal combination of cushioning and support.

Questions & Answers

  • What is a medium-soft mattress?

    A medium-soft mattress is in the middle of the soft and medium-firmness spectrum. In other words, while it is softer than a soft mattress, it nevertheless provides more support than a soft mattress.

  • Is a medium-soft mattress the best option for me?

    The "best" option ultimately comes down to personal preference and body mechanics. For side sleepers, a medium or soft mattress might be the ideal choice. Since your shoulders and hips bear the bulk of your body weight when sleeping on your side, a mattress with moderate softness can help alleviate pressure points by cradling those areas. The plush cushioning allows your shoulders and hips to sink in slightly, promoting proper spinal alignment and reducing the strain on these sensitive regions.

  • What distinguishes a medium from a medium-soft mattress?

    A medium mattress provides an even balance of cushioning and support, while a medium-soft mattress has a plusher, more conforming feel on top with slightly less underlying support.

  • Will a medium-soft mattress provide enough support?

    Yes, quality medium-soft mattresses have durable support cores, usually made of pocketed coils or high-density foams, to prevent excessive sinkage while relieving pressure points.

  • Are medium-soft mattresses good for back pain?

    For some sleepers, the pressure relief of a medium-soft mattress can help reduce back pain. But proper spinal alignment is also important, so a medium may provide better support for others.
