Guide to Choosing a Latex Mattress for Heavier People (over 16st / 100kg)



When selecting a latex mattress for individuals weighing between 16st (100kg) and 20st (120kg), it's essential to consider firmness, durability, and support. People in this weight range need a mattress that can provide adequate support to prevent discomfort, poor posture, and sagging.

Here’s a detailed guide to help you make the best choice

Firmness Level

For individuals weighing 16st (100kg) to 20st (120kg), a firm or extra firm mattress is crucial. Softer mattresses may cause excessive sinking, leading to misalignment of the spine. A firm mattress helps keep the body properly supported, ensuring better posture and reducing pressure points, especially in areas like the hips and lower back. 

Mattress Thickness

Heavier individuals generally require a thicker mattress to avoid sinking too deeply, which could cause discomfort and negatively impact spinal alignment. A mattress thickness of 9 to 12 inches (22 to 30 cm) is ideal for people weighing 16 st (100 kg) or more. A thicker mattress helps distribute weight evenly and ensures longevity.

Latex Material

100% Organic GOLS Dunlop latex is made of the sap of a rubber tree, and it is the best material used in bedding. Latex is biodegradable, has optimum elasticity and flexibility, and conforms to your body shape instantly, giving superb comfort and excellent support. It is naturally breathable, eliminating sweating and overheating.

Coconut Coir Fibre

100% Organic GOTS Coconut Coir fibre is a natural product derived from the husk of coconuts. It provides a sturdy and firm foundation for mattresses; its natural resilience helps maintain the structural integrity of the mattress, offering support to sleepers without excessive sinking. The structure of coir incorporates air pockets, which promotes air circulation throughout the mattress.

Support Layer and Zoned Design

Zoned support, where different areas of the mattress have varying levels of firmness, is particularly important for heavier individuals. Zoned latex mattresses feature firmer support in the middle (around the lumbar and lower back) and softer zones at the shoulders and legs, helping maintain proper alignment and pressure relief. Coconut coir mattresses are usually mono-zoned because coir is a tough material, and latex, being naturally responsive, provides the support needed without the need for zoning.

Durability and Longevity

A mattress for heavier individuals needs to be durable to withstand more pressure over time. Latex is naturally durable, but adding layers of coir (coconut fibre) increases the mattress's strength and resistance to wear. Coir helps prevent sagging and maintains firmness, making it an excellent option for people who weigh 16st (100kg) and up.

Motion Isolation

If you share a bed with a partner, motion isolation is crucial. Latex mattresses are excellent at reducing disturbances caused by movement, ensuring that both you and your partner can sleep undisturbed throughout the night.
