Duvalay began with a problem every caravanning family knows too well: uncomfortable beds. While holidaying with their young children, founders Liz and Alan Colleran came up with a simple but revolutionary idea – a luxury memory foam mattress topper that could roll out easily and transform any sleep space. This led to the creation of the iconic Duvalay Sleeping Bag – an innovative, patented and multi-award-winning design that combines a duvet and topper in one. What started as a homemade solution quickly captured attention, leading to their successful pitch on Dragons’ Den and a game-changing investment that accelerated their journey.
From that moment, Duvalay’s growth was rapid. The business evolved from a clever concept into a household name, trusted by thousands of customers across the UK and beyond. Collaborations with leading manufacturers like the Swift Group helped bring Duvalay’s award-winning sleep solutions into motorhomes, caravans, and campervans across the country. Our innovative designs now feature in homes, holiday parks, and even yachts – anywhere people value a great night’s sleep.
Despite our expansion, some things haven’t changed. Every single Duvalay product is still handmade with care in Yorkshire using only the highest quality materials. We’re proud to support British manufacturing and work closely with local suppliers to maintain the craftsmanship and sustainability that set our products apart.

At our core, we’re a business driven by innovation and care – for comfort, quality, and our customers. Whether you’re upgrading your touring adventures, revamping your sleep at home, or kitting out a holiday lodge, we put your sleep experience at the heart of everything we do.
Duvalay remains a true family business, now with sons William and Thomas stepping into key roles to help shape the future. Together, we’re proud to continue building a brand that’s trusted by generations – delivering the comfort of home, wherever life takes you.
