Demko Organic Coir Mattress ProLuxe A Junior Dual Firmness | Firm Vegan Tencel Cover

The Junior Firm Mattress is specifically designed to provide the robust support necessary for young children during critical stages of bone development. By offering a firmer sleeping surface, it ensures proper skeletal alignment and structural integrity throughout the night. This mattress is also an excellent choice for lighter-weight adults who prefer a more supportive, firm feel to maintain a healthy sleeping posture.

This mattress prioritises physiological health and environmental purity, creating a clean foundation for restorative rest. It is engineered to remain highly breathable, utilising moisture-wicking materials that regulate temperature for a consistent, comfortable sleep climate. To suit individual preferences and health requirements, the mattress is available with two premium cover systems: a high-tech Vegan Cover featuring probiotic allergen protection, and a luxurious Organic Cover crafted from GOTS-certified natural fibres.

The firm core works in harmony with these advanced covers to prevent the "sinking" sensation common in softer mattresses, ensuring that the airways remain open and the spine is supported. Whether chosen for a growing child or a wellness-focused adult, this mattress delivers a non-toxic, chemical-free environment that supports long-term physical wellbeing.
