Our mattress protectors do exactly that - keeping the mattress underneath cleaner and fresher and extending its life. To help ensure freshness the fabric is treated with innovative antimicrobial technology Micro-Fresh which inhibits the growth of bacteria that can cause odours and is gentle and kind to skin.An elasticated cotton skirt keeps the protector in place and the unique elasticated side seams stretch to the depth of the mattress to keep corners neat and prevent gathering helping to create a smoother finish when dressing the bed. Simply layer directly onto your mattress before covering with a normal bedsheet.
