Exploring Different Types of Super King Mattresses

We also sell super king size mattresses in a range of springs including:

  • Pocket Spring Super King Size Mattresses where individual pocket springs respond to the pressure applied in that area making them a wonderful choice for co sleepers where one is restless or of different weight.
  • Traditional Spring Super King Size Mattresses where each spring moves independently of one another offering personalised that moves with the contours of your body.

Consider factors such as firmness level, material composition, and breathability to find the perfect mattress for your preferences.

  • Soft Super King Size Mattresses and Medium Super King Size Mattresses - If you prefer sleeping on your side, a soft or medium-tension super king mattress could be ideal. These softer mattresses give your joints the support they need, relieving pressure as you sleep. For those who shift positions often during the night, a medium comfort grade is usually a better choice. Memory foam is a great choice for sleepers who change positions a lot.
  • Firm Super King Size Mattresses and Extra Firm Super King Size Mattresses (orthopaedic) - If you sleep mostly on your front or back, a firm mattress is probably the best choice for you. Firmer mattresses spread out body weight, helping to ease pressure and give more support to the spine and joints. A firm or extra firm mattress could be a great option for those seeking extra spinal support for a comfortable night’s sleep. Pocket spring options are a great choice.

Spacious super kings (180 x 200 mattress)

Depending on your bedroom size and personal preferences, you can choose the largest mattress size that best suits your needs. Superking mattresses are the epitome of luxury, providing generous dimensions. Measuring 180cm x 200cm, they provide even more space for a truly luxurious sleep experience. They are great for couples, families, or anyone who wants lots of space to stretch out and relax.

Achieving a Restful Night’s Sleep
