King vs Queen: The Real Differences

Price difference: Kings typically cost 20-35% more than queens in the same model.

Room requirements: A king in a 3m x 3m room leaves almost no space for bedside tables. Measure your room before deciding.

When to Choose Queen

Bedroom under 12 square metres, partners sleep relatively still, budget is primary concern, or you move house frequently.

When to Choose King

Restless sleepers, co-sleeping with children or pets, bedroom is 13+ square metres, or you value personal space during sleep.
