Treated to resist the build-up of allergy causing nasties Allergy sufferers have a tough time of it. This clever duvet is treated with Sanitized to protect it from the moisture evaporating from our bodies as we sleep. This moisture can harbour bacteria, attracting allergy causing nasties such as moulds & mites. A Sanitized treated duvet stays hygienically clean for a more peaceful & healthy night's sleep. Even with specialist technology there's still oodles of comfort; the soft, springy microfibre & 250 thread count cotton case means sweet dreams for anyone cuddling up under this duvet.
