The Bed Studio approach

Understand Our Support First™ System

Four connected pillars explain how a mattress is engineered, how it feels and how it works as a whole. Together, they give you a clearer way to choose.

01Support First™EngineeringUnderstand what supports you.Understand how the support core responds to your body.Explore engineering

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.

02Support First™Calibrated FeelCushioning designed to work with support.Materials, thicknesses and firmnesses selected to complement the chosen support core.Explore calibrated feel

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.

03Support First™ArchitectureEvery component. One complete mattress.Bring the core, feel layers, fabrics and construction together, with every layer serving a purpose.Explore architecture

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.

04Support First™MethodologyUnderstand your bed. Choose with clarity.A clear buying journey, from your first question to your completed purchase, online or in-store.Explore methodology

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.

Ratings reflect Kiran Sales Group’s internal assessments and have not been independently verified.

Why we don’t recommend foam or fibre as a core: they make good comfort layers, but as a support core they compress under pressure, retain heat and fatigue faster than a spring system.

A qualitative comparison of support-system design, assuming comparable mattress quality. Comfort layers, materials and overall construction also influence real-world performance. “Recommended” reflects the Support-First philosophy, not a judgement of any individual mattress.

Once You Understand Support First™, Choosing Becomes Easier.

Look beyond Firm, Medium and Plush labels. Understand the support system, see how the layers work together and choose the feel you prefer.

Best of Both™Where Our Support First™ Journey Began

Best of Both™ puts Support First™ into practice. It combines MiraCoil® and Pocket Coil in one support system, with calibrated feel layers designed to complement that foundation. Together, these elements form one complete mattress design.

Best of Both™ comes with one calibrated feel, making your choice simpler.

Two spring technologies. One integrated design. One calibrated feel.
