These pillows were due for delivery to Rosebys but they went into administration and hence this low low price. These are made from high density memory foam clusters which provide firm support for your neck and head. The clusters are then encased in a 1.5cms thick memory foam layer which adds a softer texture. The 3rd layer is a fine anti wear cotton mesh which prevents friction wear from head movement. Finally a washable zippered cover treated with "ULTRAFRESH" finishes off this unique item. No shortcuts have been taken to save money on this product. Please allow 3 days for pillows to air before use. Please note all new memory foam products will have an odour to which some people may be more sensitive to than others. Please take this into account as we will not accept returns based on odour. BEWARE of inferior pillows for sale which may look the same but use very low density foam and thus the pillows provide no support or "memory" effect!!!.
