What you should consider before purchasing a mattress.
A mattress should feel right for the way you sleep and the space you are furnishing. This guide is designed to help you compare sizes, mattress styles, and comfort options more clearly before making your choice.
At Sleep Design Beds, we focus on comfortable, well-considered bedroom products that balance support, practicality, and a polished finished look.
A better way to choose the right mattress
Buying a mattress is not only about picking a standard size. It is also about finding the right balance of support, comfort, and suitability for your room and lifestyle.
Some sleepers want a softer feel, some prefer firmer support, and others want a balanced feel that works well every night. Understanding mattress dimensions, construction, and firmness can make the choice much easier.

Why Mattresses Settle Over Time
Mattresses naturally settle slightly over time, which is a normal part of regular use.
This can happen as:
- The mattress adjusts to your body shape
- Comfort layers relax with use
- Natural materials compress slightly over time
Choosing the Right Firmness
Firmness is a matter of personal preference, so there is no single “best” option. The right choice depends on how you sleep and the level of support you find most comfortable.
Soft to Medium: Often preferred by side sleepers who want more cushioning.
Medium: A balanced feel that suits many sleepers
Medium to Firm: Commonly chosen by back sleepers who need extra support. Often referred to as orthopaedic.
Firm: Suitable for heavier sleepers or those who prefer a sturdier, more supportive feel. Also known as orthopaedic support.
A good quality bed base will also help your mattress perform properly and maintain its support over time.
