Why get a king size memory foam mattress?

Ideal for side sleepers, back snoozers and anyone who loves belly-down naps, these mattresses contour to your body with pressure-relieving layers that ease tension. They're a great choice if you have back aches or joint pain. Plus, they'll help keep your spine aligned with zoned support across high-pressure areas.

Key features and benefits:

• Fits standard king beds for spacious sleep
• Offers pressure-relieving comfort layers to reduce joint stress
• Provides zoned and orthopaedic support for spine alignment
• Choose from breathable and cooling options to regulate temperature, humidity
• Available in medium, firm and soft firmness levels for personalised comfort

If you're a light or restless sleeper, memory foam's motion isolation will help reduce disturbance for those sharing a bed with you. We also have mattresses that come with breathable fabric covers and cooling tech to prevent overheating through the night.
