Our king-size memory mattresses are available in all our most popular firmness levels, including:

• Soft
• Soft-medium
• Medium
• Medium-firm
• Firm

Something you might see with memory foam is that it might be described as 'low density' or 'high density'. This relates directly to the firmness levels, with a higher density mattress featuring more foam per cubic foot, which makes it heavier and more supportive. Lower densities, such as soft memory foam mattresses, will return to their original shape faster!

So, whether you want the extra support a firm king-size memory foam mattress provides or would rather splurge on the comfort of a softer rating, our range has something for every sleeper.
