What should I look for when buying a new mattress?

Six key criteria when buying a mattress: material, firmness, lifespan, trial period, ventilation and certifications. 

• Material + certification: OEKO-TEX®, GOTS or Eurolatex are signs of quality and safety
• Firmness: match to weight and sleeping position via the free Mattress Test
