Microfibre Pillows are exceptionally soft and are fabulous for people that suffer from allergies or asthma as they can be regularly machine washed and tumble dried (without going lumpy). They have a 300 threadcount cotton japara cover with a walled and piped construction. These pillows are anti-microbial, hypo-allergenic, odourless, dust mite resistant and have a generous filling. To help extend the life of your pillow we recommend that you use pillow protectors to protect the cover.
