The Obaby airflow pocket spring mattress will provide your child with optimum comfort and support. The HD individual pocketed springs work independently and the eco uffibre surround has a unique open cell structure that reacts and responds to the baby's body heat and weight by moulding to the contours of the body, therefore allowing the perfect airflow and keeping the baby's skin nice and soft. Also with added protection, the mattress comes with a non-removable “care cover”, which is water repellent and helps to keep the interior nice and dry, giving your mattress that extra long-life protection. The luxury pocket mattress has a soft micro fresh removable fabric cover, that has the benefits of the mattress cover washable at 40degrees and is totally hypo-allergenic, anti allergy & anti bacterialmade to prevent dead skin cells and body oils from penetrating the mattress and attracting dust mites and other microscopic organisms that can cause allergic reactions.
