Description

The Blackwell - Structured Support, Elevated Refinement

The Blackwell Wool Mattress sits proudly at the centre of our Artisan Collection, delivering a refined balance of elevated support, natural breathability, and long-lasting resilience. Handcrafted in the UK and measuring around 31cm in depth, it’s available in Soft, Regular, and Firm tensions to give you a tailored level of comfort and support.

Its precision 2000-count calico pocket spring system (King) provides responsive, full-body support, adjusting intuitively as you move to maintain healthy alignment and minimise pressure points. Above this, a curated blend of Wool ID® traceable British wool and breathable cotton creates a naturally temperature-regulating sleep surface that stays fresh, cool, and comfortable throughout the night.

A defining feature of the Blackwell is its supportive layer of white cattle hair - a traditional, artisan-grade material prized for its resilience and airflow. It adds structure and lift, preventing the ‘sink’ sometimes found in softer natural mattresses, while still delivering luxurious comfort.

Wrapped in a Merino-rich, naturally fire-resistant ticking, the Blackwell is completely free from synthetic foams, glues, and chemical fire retardants, making it an excellent choice for sensitive sleepers or anyone seeking a cleaner, healthier sleep environment.

The perfect match for those who value resilience, breathability, and expertly crafted natural support.

Care Instructions

Letting your mattress settle:

When your mattress arrives remove all packaging to allow the mattress to air. Your mattress may seem shorter than the base its on. Once unpacked, the mattress will gradually settle and return to full size. If you find that the mattress is settling unevenly, turn and rotate the mattress.

Turning the mattress:

We recommend turning your mattress regularly for the first 12 weeks of arriving, after that we would recommend turning it every 3 months.

Cleaning your mattress:

Do not use a vacuum cleaner on your mattress. Use a soft brush to remove any fluff. In case of spillage, spot dry the liquid quickly with a dry cloth.

Built from the inside out with natural wellness in mind. Our wool mattresses help reduce allergens and resist dust mites—creating a cleaner, healthier sleep from the very first night.
Environmentally Friendly & Sustainable

No harmful chemicals or fire retardant sprays are used in our mattresses, giving you peace of mind as you sleep in a pure and natural environment.

Mattress Recycling

At Woolroom, sustainability runs through everything we do, including what happens to your old mattress. 100% of returned mattresses are kept out of landfill, so the materials can be reused.

How our mattress recycling works

Careful collection and dismantling: When your old mattress comes back to us, our delivery partners collect it and take it to a specialist recycling centre. Each mattress is handled carefully and prepared so the materials can be recovered.
Cleaned, checked and sorted: Every mattress is checked, then taken apart by hand into separate parts. Each material is cleaned, sorted and processed so it can be reused wherever possible.
Given a second life: Every week, over 16,000 mattresses are recycled in this way. Usable materials like springs, foam and fibres are given a second life and turned into new products in other industries.
