Design Process

Creating Ergonomic Support

Developed in line with recommendations from professionals in the physiotherapy and chiropractic industry, The Terra Mattress is a firm sleeping surface that optimises proper spinal alignment and sleeping posture, while still delivering great comfort.

We wanted to cater to users who are used to sleeping on ultra-firm spring mattresses, or are transiting to a full foam mattress for the first time. Leveraging on our high competencies in Latex production, we combined two uniquely formulated densities of 100% Natural Latex to combine perfectly with our Memory Foam. The result is an incredibly firm yet responsive sleeping surface that doesn't feel like you're sleeping on rocks.

How does it feel

Firmness: 9/10

A firm surface that is also responsive due to bouncy latex, making it great for back sleepers and heavier side sleepers.

Let’s look under the covers.

  • C. The Cover:

    Italian-made Microtencel

    Incredibly soft and plush microtencel with embedded silver threading for added antimicrobial properties and odour reduction.

  • 1. Ultra Density Latex Layer:

    100% Natural Latex - 3cm

    Ensures spinal alignment and maintains good sleeping posture throughout the night

  • 2. High Density Latex Layer:

    100% Natural Latex - 5cm

    Provides ergonomic support for the entire body without sinking and sagging, specially targeted at areas around the lower back.

  • 3. Ultra Density Memory Foam Layer:

    Ultra Premium Memory Foam - 5cm

    Offers pressure relieving support, gently hugging you to sleep.

  • 4. The Transition Layer:

    High Resiliency Transition Foam - 7cm

    Provides additional, deeper levels of comfort and support before easing into the base foam.

  • 5. The Foundation:

    Ultra High Density BaseCore Foam - 10cm

    Foundational base for added lift and zero motion transfer when you toss and turn.


Bedtimes without springs

Why use foams and not springs?

Through our research and extensive testing, we find that most springs tend to give way much faster due to the constant gravitational pressure from your body, and offer sub-par weight distribution as compared to high quality foams.

We wanted a core foundation that is supportive, resilient, durable, and eliminates motion transfer - which is best achieved through our premium quality, high density PU foam base. Furthermore, our foam components react to the body’s weight and heat in a way that springs can never achieve. Imagine having a million cells distributing the weight evenly across your body, offering support at the most critical points - it’s a no-brainer!


Responsive spinal alignment

100% Natural Latex layers helps create a firm surface that is quick to recover, so you wouldn’t feel like you’ll sleeping on a bed of rocks. Bouncy latex helps ensure spinal alignment and maintains good sleeping posture throughout the night.


Better manoeuvrability

The extra firm surface of the Terra allows better movement on the mattress, perfect for sleepers who toss and turn throughout the night. It is also great for extended sitting and sleeping hours, and makes it easy to get in and out of bed.


Advanced latex technology

Double thick layers of latex offer a premium surface that is extremely durable at great value. Dual densities help create ergonomic support for the entire body without sinking and sagging, specially targeted at areas around the lower back.
