Open coil mattresses use a single continuous wire or linked springs throughout the mattress. While this offers basic support, movement on one side tends to transfer across the entire surface.

Pocket sprung mattresses, on the other hand, feature individual springs housed in fabric pockets. Each spring moves independently, offering superior support, reduced motion transfer, and better contouring to your body.

At Gemini Sleep, we craft all our pocket sprung mattresses for optimal comfort, durability, and a more personalised sleep experience.

Spring count refers to the number of individual springs inside a pocket sprung mattress - usually measured based on a standard king size (150 x 200 cm).

Generally, a higher spring count means more individual support points, allowing the mattress to contour more precisely to your body and minimise motion transfer.

At Gemini Sleep, we carefully select spring counts to balance comfort, durability, and support. It’s not just about numbers - it’s about how the mattress feels and performs as a whole.

Here’s a quick guide:

• Up to 1,000 springs – Standard support, suitable for occasional use or lighter sleepers
• 1,000–2,000 springs – Enhanced comfort and support, ideal for most sleepers
• 2,000+ springs – Precision support and luxury feel, great for couples and those seeking superior pressure relief

Firmness is a personal preference, but it also depends on how you sleep.

• Soft to Medium: Ideal for side sleepers or those who prefer a more cushioned feel, allowing shoulders and hips to sink in comfortably.
• Medium to Firm: A balanced feel that suits most sleepers, especially those who change positions throughout the night.
• Firm to Extra Firm: Best for back or stomach sleepers, or those needing extra support, particularly for spinal alignment.

At Gemini Sleep, our curated range ensures each firmness level combines handcrafted comfort with considered support.

To prolong the life and comfort of your Gemini Sleep mattress:

• Rotate regularly: Every 3–6 months, rotate head-to-toe to promote even wear.
• Use a breathable mattress protector: This keeps the surface clean and guards against moisture and spills.
• Let it breathe: Occasionally airing out your mattress helps release trapped moisture and maintain freshness.
• Support matters: Ensure your mattress is placed on a sturdy, ventilated base to support its structure and airflow.

Each Gemini Sleep mattress is crafted to last—proper care ensures it performs beautifully for years to come.
