Raskelf Memory Foam pitched a zip up memory foam mattress and duvet combo in series 9 of Dragons' Den and walked out with Hilary Devey's backing. Years later the question is simple: did it last? The short answer is yes, and the company behind it has grown well beyond the single product that got it through the Den's doors.
The Short Answer
Raskelf is still trading. The founders, Alan and Elizabeth Colleran, built the original memory foam sleeping bag concept into a wider group of sleep product brands, and that group is still manufacturing and selling today. This is one of the clearer survival stories in our index. The product that started it all became the seed of something bigger rather than a one hit appearance.
The Dragons' Den Pitch
The Collerans appeared in series 9, episode 2, pitching their zip up memory foam mattress and duvet combo under the Raskelf name. It fell into the home and lifestyle category, a crowded space where Dragons tend to ask hard questions about margins and manufacturing costs before they ask anything else.
The founders asked for 80,000 pounds in exchange for 26 percent of the business. That is a fairly steep equity give for the amount on the table, which usually signals either an early stage business without much trading history behind it, or founders who wanted the money badly enough to make the maths easy for a Dragon to say yes to.
The Deal That Got Done
Hilary Devey put up the full 80,000 pounds for the 26 percent stake the founders offered. No renegotiation, no haggling over the split. Devey made her name in logistics and freight, not sleep products, but she was known on the panel for backing founders with manufacturing grit rather than founders with the flashiest pitch deck, and a zip up mattress system built by hand in Yorkshire fits that profile well.
For the Collerans, closing at the terms they walked in with meant they kept the deal simple and the ownership structure clean from day one, which likely made it easier to build on afterwards.
What Happened After the Cameras Stopped
The years since the episode aired tell the more interesting part of the story. Rather than staying a single product business, the Raskelf name became the anchor of a wider group. The founders brought several sleep related brands together, including Duvalay and Summerby Sleep, and later folded in Nursery Connections, a baby mattress manufacturer, after an acquisition.
That consolidation turned a Dragons' Den mattress pitch into a proper manufacturing group with more than 120 staff working across two sites in West Yorkshire and Northamptonshire. The group has also been through a formal restructure in recent years, the kind of corporate move that usually accompanies real scale rather than decline, aimed at organising the various brands under one clearer structure going forward.
Where to Find Raskelf Today
The group operates its own website at raskelfgroup.co.uk, where you can see the full family of brands that grew out of the original Dragons' Den pitch. There is no indication the products are sold through Amazon, so the direct route through the group's own sites and its retail, leisure and hospitality trade relationships is the way to buy.
For a business that started with one entrepreneur explaining a zip up sleeping bag to five sceptical investors, ending up as a multi site manufacturing group employing well over a hundred people is about as strong an outcome as the Den produces.
Common Questions
Is the original Raskelf zip up mattress still sold? The core sleeping bag style memory foam concept lives on within the Raskelf Group's broader Duvalay range, rather than being sold as a standalone product under the original branding alone.
Is Hilary Devey still involved with Raskelf? Devey passed away in 2022. Her equity stake and the investment she made remain part of the company's history, and the business has continued operating and growing since then under the Colleran family's leadership.
The Bottom Line
Raskelf pitched in series 9 for 80,000 pounds at 26 percent, got the full amount from Hilary Devey on those exact terms, and used the investment as a springboard rather than an endpoint. Today the founders run a wider sleep products group built on the original idea, employing well over a hundred people across two English manufacturing sites. If you came here wondering whether the mattress from the Den is still around in some form, it is, just wearing a bigger company's name.
