Why choose the Premium?

Our Premium mattress-in-a-box is a Foam Encapsulated Mattress. This means that the inner layers of filling are encased within a foam border, which supports them.

This outer, encapsulating foam border acts as a box which reinforces the inner filling, but also makes the whole mattress more durable. On top of that, it keeps the mattress from sagging and prevents that annoying ‘roll-off’ feeling.

Mattress Composition

The Premium is designed to provide you support where you need it most, ensuring you will wake up and feel great. Discover what’s inside our Premium mattress, and how its layers supports your body.

Sleepology top cover

Breathable and hypoallergenic sleeping surface, soft to the touch

KGEL

Gel-infused viscoelastic foam, designed to reduce heat build-up

V40 Memory Foam

Memory foam layer, providing relief and keeping the pressure off

36R Foam

Slightly denser foam, designed to provide pressure relief to each area of your body

Pocket springs

encapsulated with 40H foam

1,000 individual springs for King size, approx. 600 springs for other sizes, surrounded by a supportive foam border

F32 Reflex Foam

High-density, responsive polyurethane foam, providing firmness and support

Enhanced borders

Designed to provide optimal support to all mattress layers and the encapsulation

Benefits of the Premium

The Premium is definitely our sturdiest and supportive mattress thanks to the foam encapsulation. Here’s a full list of all the advantages you get when choosing the Premium.

No sagging

The entire mattress is reinforced with high-density support foam

Support throughout

The sturdy foam border prevents ‘rolling-off’. This offers consistent edge-to-edge support across the whole mattress surface, regardless of whether you sleep alone or with a partner.

No turning mattress

The Premium mattress layers are organised in a way that not only provide you the ultimate support and sleeping experience, but also eliminate any need to turn your mattress.

The perfect foam combination

The Premium combines different types of foam with different features and benefits:

Superflex foam will offer you softer and gentle support.
Memory foam adapts to your body's movements while you sleep, offering responsive comfort all the times.
Reflex foam is a higher density type of foam which offers greater support for your sleep.

Thoroughly tested for you
