Harrison Spinks Collingham 3250 Pocket Mattress - UK Emperor

• Cover. A soft blend of wool and viscose that is fire resistant and chemical free. That means no chemical fire retardant treatments against your skin.
• Comfort layer. Traceable British wool forms the soft cushioning layer. Wool naturally regulates temperature, which means less overheating on warm nights.
• Interior blend. A blend of cotton, hemp and flax sits within the interior. These natural fibres add breathable padding between you and the springs.
• Support system. 2500 high density pocket springs, each 100% glue free and encased in its own fabric pocket, including award winning Advanced Cortec pocket springs. Individual pockets mean each spring moves independently, so you feel less of your partner's movement.
