Pure, Safe and Supportive Sleep for Growing Babies

Introducing our Premium Organic Latex Cot Mattress — offering the same quality, comfort, and sustainability as our renowned adult mattresses, now perfectly designed for your baby's first bed. With 45 years of craftsmanship, Zentai Living brings you a 100% natural, breathable, chemical-free cot mattress, assembled and designed in Byron Bay from certified organic materials, nurturing your child from newborn through to toddlerhood.

GOLS-Certified Organic Latex Core for Every Stage

Our cot mattresses feature a dual-sided, GOLS-certified organic latex core — giving your baby two comfort options in one mattress. Two 5cm layers, one extra firm and one medium-firm, are bonded using organic liquid latex only, with no synthetic glues or adhesives. We do not use coconut fibre, as this is a premium baby product. Cot Mattress Core:
  • Infant side (0–12 months): 5cm extra firm, for safe, flat, supportive sleep. Firmness is designed in line with the Australian and New Zealand voluntary test method for infant sleep surface firmness, so you can be confident your baby is sleeping safely and comfortably.
  • Toddler side (12 months–3 years): 5cm medium-firm, for supportive sleep and healthy spinal alignment.
  • The latex core is encased in a zip-off GOTS-certified organic cotton jersey inner lining (washable).

GOTS-Certified Organic Cotton Cover Construction

  • Knitted 400gsm certified organic cotton (outer layer)
  • 400gsm quilted certified organic cotton wadding
  • Double-sided quilting, top and bottom
  • Certified organic cotton woven internal backing fabric
  • Latex core covered in protective jersey zip-off lining (washable)
  • 3-sided YKK zip for easy rotation or flipping of the latex core. Outer cover removable for sunning and airing (the outer cover is not washable).

Why Choose an Organic Latex Cot Mattress

  • GOLS-Certified Organic Latex — the cot mattress core is made from pure, sustainably sourced 100% organic latex, providing supportive, breathable, chemical-free comfort for babies.
  • GOTS-Certified Organic Cotton — the cover is crafted from premium, thick organic cotton knit fabric and wadding, offering softness, breathability, and natural protection.
  • Because every component is drawn from organic, natural sources, your baby sleeps in an environment with exceptionally low VOC levels. There are no synthetic additives or hidden toxins in the build — just pure materials from core to cover.
  • Crafted using only natural materials — no polyurethane foams, memory foams, springs, or harmful chemicals — creating a safe, non-toxic sleep environment for little ones.
  • Assembled and designed in Byron Bay, our premium cot mattress is 100% natural, breathable and chemical-free, supporting your child's development from infancy through toddlerhood.

Mattress Protector

The fitted mattress protector shown in some of the photographs is sold separately and is not included with this mattress. A waterproof protector is recommended to keep the organic cotton cover clean, as the outer quilted cover cannot be washed.

Warranties
All Zentai Living products come with warranties. Please check below for details:

  • Latex Mattresses: 10 years
  • Toppers: 4 years
  • Futons: 24 months
  • Furniture: 12 months
  • Most accessories: 3–5 years
  • Pocket Spring mattresses: 2 years

Your Zentai Living latex mattress is designed for comfort, support, and durability. With proper care, it can provide you with many years of healthy, restful sleep. To protect your investment and ensure your warranty remains valid, please follow these care and maintenance recommendations:


1. Mattress Support

  • Always place your mattress on a strong, flat, and well-ventilated base.

  • Slatted bases should have gaps no wider than 7 cm to prevent sagging.

  • Avoid placing the mattress directly on the floor or solid surfaces without ventilation, as this may encourage moisture build-up.


2. Rotation & Handling

  • Rotate your mattress every 3 months (head to foot). This ensures even wear and helps maintain shape and comfort.

  • Do not flip one-sided models; double-sided latex mattresses may be flipped and rotated for maximum longevity.

  • When moving, never fold or bend your mattress. Carry it on its side with assistance.


3. Protection & Cleaning

  • Use a breathable, washable mattress protector to guard against spills, stains, and dust mites.

  • Do not use plastic or non-breathable covers, as latex needs airflow.

  • Spot clean only: use mild soap with a damp cloth and allow to air-dry completely before re-covering.

  • Never soak, steam clean, or machine wash the latex core.


4. Room Environment

  • Maintain a cool, dry, and well-ventilated bedroom.

  • Avoid prolonged exposure to direct sunlight or heat, which can degrade natural latex.

  • If possible, air out your mattress for a few hours every few months by removing bedding and allowing airflow.


5. Everyday Use

  • Do not jump, stand, or apply sharp pressure to the mattress, as this may damage the latex core.

  • Keep pets with sharp claws away from the mattress surface.

  • Always use fitted sheets to reduce friction and wear.


6. Warranty Conditions Reminder

Following these care steps is essential to keeping your 10-year limited warranty valid. Damage caused by misuse, neglect, or failure to follow care instructions is not covered.

Why Organic?

Zentai Living’s organic latex range is constructed of raw materials that have never been touched by pesticides, fertilisers and chemicals. Additionally, the growing process for these raw materials involves one or more sustainable energy sources. Our organic latex mattresses are GOLS (Global Organic Latex Standard) certified. This means they’ve gone through a rigorous screening process from the planting and gathering of raw materials through the manufacturing process to verify that sustainable processing methods are used in order to gather organic ingredients and/or raw materials.

Furthermore, Zentai’s organic latex mattresses are made with GOTS (The Global Organic Textile Standard) certified organic 100% cotton covers. This standard sets the requirements that ensure organic status of textiles, from harvesting of the raw materials, through environmentally and socially responsible manufacturing up to labelling, in order to provide a credible assurance to the end consumer.

Enjoy natural, restorative sleep with our Certified Organic Latex Mattresses, crafted from GOLS-certified organic latex for firm, breathable support. Ideal for trundles or minimalist setups, this low-profile design offers comfort without bulk, making it perfect for both adults and children.

Frequently Asked Questions

faqs Zentai Living was founded in 1981 in Sydney. A few years later the current owner relocated to beautiful Byron Bay on the North Coast of NSW.

Yes. Our latex core is GOLS-certified, meaning it's made from sustainably sourced natural latex without synthetic fillers, foams, or harmful chemicals — creating a breathable, low-VOC sleep surface for infants and toddlers.

Newborns need a firm, flat sleep surface for safety. Our infant side is extra firm and designed in line with the Australian and New Zealand voluntary test method for infant sleep surface firmness.

The outer quilted cover is non-washable — it's designed to be rotated and aired out via the 3-sided zip rather than laundered. The inner jersey lining around the latex core is washable. We recommend a waterproof mattress protector to keep the outer cover clean.

No. The fitted protector shown in some of the product photographs is sold separately. We recommend pairing this mattress with a waterproof cot protector, as the outer quilted cover cannot be washed.

The dual-sided design means you can transition from the extra-firm infant side to the medium-firm toddler side as your child grows, typically from around 12 months.
