The Woolsleeper Pillow Top mattress has been created by Hypnos for an optimum sustainable sleep solution. The no turn design ensures supreme comfort with minimum fuss and every detail considered, including sustainably-sourced and fully recyclable materials. The 150cm Woolsleepers Pillow Top contains 660g wool which is fully traceable back to the individual farm, while an unbleached cotton and viscose surface provides a luxurious, breathable, and hygienic sleep. The Re Active Pro™ pocket spring core is specially engineered to deliver ultimate comfort, time after time. GRS Dual density polyester is made from recycled plastic bottles, and our 150cm mattress contains over 230 recycled 500ml plastic bottles that otherwise would have gone to landfill. Each mattress is also constructed with a contract Triple Edge Protection™ to provide true edge-to-edge support. Horizontal handles ease mattress positioning on the bed base.
