The Future of Sleep Is Here.
And It’s All About Our
Support First™ System.

We consider how your body and mattress work together. This is where biomechanics comes in: the study of how forces act on the body. When you lie down, your weight loads the mattress and its materials respond.

We study how spring, foam and fibre support cores are built, how they carry your weight and how they respond. This guides the support systems we select and develop, starting with the core and its role in the complete mattress.

Think of a chair: the cushion shapes how it feels, while the structure helps determine how it carries you. Softness is only part of the picture. Firm, Medium and Plush describe surface feel; they do not explain the support underneath.

We select and configure the cushioning layers to work with the support core beneath them. The aim is a considered balance between cushioning and support. More filling does not automatically mean greater comfort, and a harder surface does not automatically mean better support.

The same cushioning layers can feel different on different cores. What you experience comes from the complete combination.

Lylax and Best of Both offer a specified Calibrated Feel for each model. Selected Serta models also offer Firm, Medium and Plush options within the same design approach. Calibrated Feel is not another name for Medium: it does not mean every model feels identical or suits every person.

Think of a car: its seats and suspension work together to shape the ride. Softer seats alone don’t tell you how the whole journey will feel.

Architecture brings together the support core, calibrated feel layers, fabrics, mattress ticking (the outer covering) and the construction that holds everything together.

We consider how these components interact, including their contribution to airflow, moisture management, hygiene and durability. In our Support First philosophy, support and hygiene are the foundations of overall comfort, with feel working alongside them.

We look beyond the feel on day one. Foam can soften and fibres can compact with use, so the materials and durability of the complete mattress matter.

Think of a home: its structure, interiors and ventilation all shape the experience of living there. The complete design matters more than any one feature.

We explain the support system, how the layers work with it and what the complete mattress offers, then guide you through the relevant options. Clear information and fewer unnecessary decisions make choosing simpler.

Best of Both has its support combination and Calibrated Feel already specified. Choose your size and configuration, then review the price and purchase details. For other models, choose your support and mattress, followed by size and any available feel options.

The journey also covers guarantee, warranty and care requirements, ownership terms, delivery and payment. You can take more time or ask for help whenever you need it. Online or in-store, the confidence comes from understanding what you are buying.

Think of a navigation app: it weighs the routes, distances and traffic for you, then shows the options that make sense. You still choose the journey, without having to study every map.
