Designed to deliver firm, stabilising support without compromising on comfort, this mattress blends European-inspired foam technology with a luxurious quilted finish for a refined, breathable sleep surface. With its elevated 250 mm profile and consistent double-sided design, the Kooi Ultra provides durable, long-lasting performance night after night. Enjoy a sleep experience that aligns your spine, reduces pressure points and enhances comfort through every movement.

Comfort level – Firm

Ideal for the following sleeping styles:

• Back sleepers
  
• Stomach sleepers
  
• Side sleepers who prefer firmer support 

Pure High-Stability Support Core

At the centre of the Kooi Ultra lies a robust high-density foam core engineered to promote healthy spinal alignment and long-term structural integrity. This pure foam foundation resists sagging, softening and compression — ensuring a supportive sleep environment throughout the lifespan of the mattress. Each night, your body is cradled with balanced pressure relief while receiving the strength and stability essential for rejuvenating rest.

Dual-Sided Pure Foam Comfort System

Designed for longevity, the Kooi Ultra features a fully double-sided construction. Both sleep surfaces include plush quilted foam layers paired with breathable soft knit fabric, offering gentle contouring and enhanced airflow. Flip the mattress periodically to refresh comfort, extend durability, and maintain the balanced feel of the support system. This two-sided approach preserves the mattress’s structure, making it ideal for sleepers seeking lasting dependability.

Zero Calcium Fillers, Zero Sagging

Unlike conventional foam mattresses that rely on calcium fillers, the Kooi Ultra is crafted exclusively from pure, premium foam. This ensures superior foam integrity, prevents breakdown, and eliminates lumps, crumbling or soft spots over time. The result is consistent, stable support and a cleaner, healthier mattress.

Quilted Breathable Sleep Surface

A luxurious quilted top and bottom layer of 30 mm pure foam combines with soft, breathable knit fabric to create a cool, soothing sleep surface. The unquilted high-soft knit border enhances airflow around the mattress, helping regulate temperature throughout the night. Enjoy a sleep surface that remains fresh, comfortable and supportive in all seasons.

Engineered for Durability and Local Comfort Needs

Built with South African sleepers in mind, the Kooi Ultra supports up to 120 kg per person per side. This makes it ideal for individuals who require firmer, more stable support and long-lasting performance. Every layer is purposefully designed to resist compression, maintain posture and deliver trustworthy nightly comfort.

Certified Safe & Hygienic Materials

As with all Kooi mattresses, the pure foam materials used in the Ultra are free from harmful chemicals and allergens, ensuring a safer sleep environment for sensitive sleepers. Enjoy peace of mind knowing your mattress contains no toxins or irritants.
