Description

The Millbrook Smooth Tech 4000 Pillow Top Mattress features luxurious natural wool fibres. Paired with unique and innovative ergonomic springs for the ultimate blissful sleep.

Sprung core

With an internal support system of 1000 ergonomic pocket springs, this mattress provides excellent care. Joined with a further 3000 Comfonomic micro springs for added support. These springs combined create a base for soothing pressure relief and optimal body alignment. Keeping your spine in correct position and easing any lingering aches. The ergonomic design ensures your body weight is evenly distributed. Reducing the risk of high pressure being held on certain areas of the body. This in turn improves your blood circulation for a healthier sleep.

Natural and luxurious

Finely filled inside the comfort layer is a unique blend of wool, cotton, silk and cashgora. Delivering a wonderful cloud-like feel as your body sinks into it. These natural fibres are exceptionally thermoregulating, providing wonderful seasonal use. Feel the relief of pressure being lifted off your body as the delicate natural fibres cuddle you each night.

Finished with a pillow top layer for additional plush cushioning that welcomes your body to cloud like bliss.

Balanced feel

Ideal medium firmness delivers soft comfort and sturdy support. The perfect choice for all types of sleepers and a great option when sharing the bed. Medium mattresses dispense soothing equal support for a cosy rest.

Lasting quality

Holding your experience at the heart of operations, Millbrook have brilliantly crafted this mattress right here in the UK. This means it meets all safety and comfort standards to offer a worry-free rest.

Designed to be single-sided, you won't have to fret about unnecessary and straining flipping. Simply rotate using the handles provided. Aim to stick to weekly rotations for the first six weeks before transitioning to monthly. Keeping up with mattress care allows for longevity. This is because it reduces the build up of dips in the surface and discolouration.

Complete with a 10 Year Warranty for even more reassurance so you can buy with confidence!
