100% Organic 'Slim Jim' Cotton & Wool Bonnel Spring Mattress

The 100% Organic “Slim Jim” Wool & Cotton Mattress has been specially designed for those seeking a slimmer-profile mattress without compromising on comfort, support, or organic quality. Combining practicality with traditional craftsmanship, the Slim Jim is the perfect solution for bunk beds, camper vans, caravans, guest rooms, children’s bedrooms, or anyone simply looking for a high-quality 100% organic mattress at an affordable price point.

Its reduced height makes it particularly ideal for bunk bed safety, helping maintain safer rail heights whilst still delivering excellent comfort and support. The slim and lightweight design also makes it perfectly suited for tighter spaces such as motorhomes, camper vans, caravans, and occasional-use sleeping areas where a full-depth mattress may not be practical.

Inside the mattress are generous layers of 300 GSM Organic Wool, providing natural comfort, breathability, and temperature regulation. Organic wool helps keep the body cool during warmer months and warm throughout winter whilst naturally wicking away moisture for a fresher and healthier sleeping environment. Unlike synthetic fillings, wool is naturally hypoallergenic and breathable, helping reduce heat and humidity build-up during the night.

At the core of the Slim Jim is a traditional 13.5 Gauge Bonnell Spring System, offering reliable, supportive comfort with excellent durability. This time-tested spring unit provides an even sleeping surface and dependable support, making it ideal for everyday use whilst keeping the mattress lightweight and practical.

The Slim Jim is a convenient one-sided non-turn mattress, designed for easy maintenance whilst still delivering excellent comfort and support. Simply rotate periodically to help maintain performance and longevity.

The mattress is beautifully finished in our luxurious 100% Organic Egyptian Cotton cover, offering a soft, breathable, and naturally comfortable sleeping surface. Traditional hand tufting secures the fillings firmly in place, improving durability whilst adding extra comfort and a classic handcrafted appearance.

Completely 100% organic and chemical free, the Slim Jim contains no foams, latex, synthetic fibres, or chemical fire retardants — just honest, traditional comfort using premium organic materials.

Whether for a bunk bed, camper van, caravan, spare room, or budget-friendly everyday mattress, the Slim Jim Organic Wool & Cotton Mattress delivers exceptional value, comfort, and practicality with the benefits of truly organic sleep.
