What types of king size mattresses are available? >
King Size Memory Foam Mattresses For the ultimate support, a king size memory foam mattress is the perfect choice. Memory foam uses your body heat to mould to your contours, providing a sleep experience customised to your needs.
King Size Pocket Sprung Mattresses A king size pocket sprung mattress is ideal for couples, featuring thousands of individually wrapped pocket springs that operate independently. This design isolates movement, ensuring a restful sleep even if you or your partner move around a lot at night.
King Size Open Coil Spring Mattresses Also known as traditional or Bonnell coil mattresses, king size open coil mattresses have a structure of interconnecting springs. This construction spreads weight evenly across the surface, offering high support at an affordable price.
King Size Latex Foam Mattresses Latex foam works similarly to memory foam by using your body heat to mould to your body, but with the added benefit of being hypoallergenic. Our king size latex foam mattresses are perfect for those with allergies, as latex foam is naturally hypoallergenic.
King Size Orthopaedic Mattresses If you suffer from a bad back or have stiff and achy joints, consider investing in a king size orthopaedic mattress. These mattresses are designed to be firmer than other types, promoting healthy spinal alignment and alleviating aches and pains.
