The Alex Daisy Organic Mattress is wrapped in a 3D knitted bamboo cotton fabric cover. We use only the highest quality non-toxic foam, especially made for your precious baby, because though most crib mattresses may look alike, they are not the same. Our all natural bamboo cotton fabric cover has been naturally treated to create a durable, firm pad that is free from chemicals, hypoallergenic, dust mite resistant, and has an open cell structure allowing for air flow. This is important as it keeps your baby cooler and dryer when they sleep, avoiding rashes on that tender skin. The Alex Daisy Mattress is a dual side infant and toddler mattress, having a 3d mesh which can be used in both summer and winter. This natural mattress bed provides maximum support, recommended by paediatricians. We know you want the best for your baby, without any compromise. It provides ideal support and comfort with all stages of infant to toddler development. The foam density is as such that it acts as little natural springs which supports your baby’s crucial spine development. Moreover, it also has excellent ventilation and breathable properties and is naturally anti-dust mite so that your baby does not suffer from any allergies. It is made for amazingly resilient long lasting use.
