Our Cook Mattress is designed with a 21cm Pocket Spring Construction system. Bonnell spring systems are created with an hourglass shape, being wider at the bottom and top. The springs are interconnected with a metal mesh, creating a durable, affordable and traditional feeling mattress without compromising on essential comfort.
The Cook mattress is designed with longevity and freshness at its forefront, with a breathable mesh shell surrounding the outer layer of the Core. This design allows for maximum airflow, transferring moisture and heat formed whilst sleeping. A mesh shell helps to create a fresh, healthier mattress for longer-lasting, more restorative nights' sleep for years to come.
The Cook mattress is finished with a 3cm deep pillowed topper. The pillowed finish provides a cosy and comfortable top layer for ultimate relaxation. Our Cook mattress topper means luxurious feeling sleep, without breaking the bank.
The Cook Mattress arrives at your door conveniently in a Flatpack Co. box. Our innovative packaging is significantly smaller than traditional mattresses, merging vacuum packing and a rolled design. This allows for easy movement upstairs, round tricky corners or through smaller door frames.
