John Marshall and Company was established over 70 years ago and is a wholly owned and operated New Zealand company with a proud reputation for delivering to specification on time anywhere around the world. John Marshall and Company desire to assist in positioning New Zealand wool as one of the world's primary processing fibres. It is our belief that in today's world, wool has a vital role to play in meeting emerging environmental demands.


Our Wool

Joma Wool® is carefully shorn from crossbred sheep, which freely roam amongst New Zealand expansive farmlands. New Zealand sheep are renowned for having the whitest, strongest and cleanest wool due to a combination of climate, care and expert farming practices.

Wool fibre has a natural curl which gives it bounce, body and soft support characteristics ideal for use in mattresses and bedding. Joma Wool® is further enhanced through a special crimping process, which we have perfected through years of research and continue to improve on through ongoing innovation.

The unique physical properties of Joma Wool® create a range of benefits for both personal wellbeing and practicality of use.

greater BULK

Joma Wool's special crimping process provides an impressive 40-50% increase in bulk with the benefit of increased wear life and added volume without weight. The crimping process increases the natural frequency of the bends or waves along the length of the wool fibres, which are then permanently heat set to predetermined limits.

strength & RESILIENCE

Joma Wool’s resilience is due to the bonds between the core fibrils. Fibrils are shaped rather like springs of a mattress and are linked together by natural chemical bonds. This bonding prevents the spirals rotating when pulled or pushed, providing Joma Wool with excellent elastic and torsional rigidity which resists packing down under pressure. 


Wool has long been valued for its outstanding insulating properties. By trapping air within its fibres, wool offers exceptional temperature regulation that keeps people cool in summer and warm in winter. Temperature changes within wool are slow and gradual, creating a stable microclimate which helps to provide a more rested night's sleep.


The natural keratin in wool means it can absorb up to 30% of its own weight in water without feeling wet. This is particularly effective towards water vapor. As humidity levels rise, wool absorbs the moisture, keeping the humidity at the surface relatively low. The absorbed moisture gets slowly diffused into the atmosphere, ensuring that a damp, clammy feeling will never be experienced with wool.

Water Repellence

Wool has the unique ability to repel liquid water yet absorb water vapour. This occurs because the outer layer of wool has a hydrophonic epicuticle which causes water to bead up and run off, while water vapour diffuses into the fibre through microscopic pores in the surface. This natural liquid repellence is an ideal attribute for mattresses and bedding.

Flame Resistance

Years of tests have continually demonstrated wool to be among the safest of bedding materials for flame resistance. The high keratin and moisture content make it naturally resistant to burning. It is difficult to set wool alight and it tends to extinguish itself. Joma Wool achieves superior flame-resistance without the need for harmful chemicals.

Allergy Free

All Joma Wool is thoroughly cleaned and is non-allergenic, making it ideal for customers who are allergic to feather and down or who suffer a reaction with synthetic bedding products. Joma Wool is also available treated with UltraFresh, an antimicrobial, antifungal treatment for added protection.


Our wool comes from farmers who abide by strict rules and regulations around animal welfare. We support careful handling of any natural resource, including our beloved sheep. We work with those who safeguard their wellbeing at every stage, and promote healthy ecosystems amongst their grazing pastures.


While we do our utmost to provide the most natural product we can, the reality is that we must also ensure Joma Wool meets today’s standards for hygiene. This means we use the smallest possible amount of chlorine during processing in order to sanitise our wool. It is simply the only viable option that exists today to achieve the hygiene required. We continue to review this process and seek alternatives, whilst maintaining a product that we believe offers the optimum balance between ‘green’ and ‘clean’.
