Who Should Choose a King Size Bed?

  • Couples: The extra 6 inches of width compared to a double makes a king size bed the standard choice for couples, allowing both sleepers to move freely without waking their partner.
  • Taller Sleepers: At 200cm long (6ft 6in), the 150x200 bed frame is essential for those who find their feet hanging off a standard double mattress.
  • Storage-Focused Homeowners: If your bedroom lacks wardrobe space, a king size ottoman bed utilizes the entire footprint of the bed for hidden storage.
  • Back Pain Sufferers: When paired with a supporting base, the best king size bed for back support provides a stable, expansive platform that works in tandem with orthopaedic mattresses to maintain spinal alignment.

  • Regular Maintenance Checks: >Every 6 months, re-check the joints and tighten any bolts that may have loosened with natural movement to prevent squeaking.
  • Fabric Care: For upholstered frames, use a soft brush or vacuum attachment weekly to remove dust; spot clean spills immediately with a damp cloth and mild detergent.
  • Ottoman Operation: If you have a storage bed, ensure you open the lift mechanism fully and never exceed the weight limit to maintain the longevity of the gas pistons.
