The Harrison Spinks Northumberland 15000 Mattress is available for purchase in-store only.

Carefully crafted and perfected, this luxurious mattress features sumptuous natural and sustainable fillings working in harmony with multiple layers of superior springs. The Northumberland features 15,000 innovative springs in queen size, including 100% recyclable, sustainable glue-free, Quad-core pocket springs and contouring Micro springs offering responsive support night and night.

Northumberland features 7 total layers of individually wrapped, glue-free pocketed springs. The result is a deeply cradling, sumptuous comfort.

Harrison Spinks is a unique offering in the world's foam-free luxury mattress market. While made using traditional methods of construction, the spirit of innovation which originally birthed the pocket spring is alive and well. Harrison Spinks not only produces their own springs in-house but the machines that produce the springs were also designed in-house. In order to achieve the remarkably thin gauge steel required for the world's highest spring counts they must run the steel through their own series of dies. The end result is a more elastic and supportive mattress, Micro springs will continue to offer years of resilient support even in the context of the natural fillings compressing. The value for money is unrivalled by their luxury competition.

So too, is the case with the entirely-natural foam-free fillings. In 2009, Harrison Spinks purchased Hornington Manor, where they operate a 300-acre farm. They rear prize-winning sheep and grow their own hemp and flax. In fact, Harrison Spinks is the UK's largest hemp producer.

Harrison Spinks mattresses are circular by design. Using only the finest in natural and sustainable materials, 100% recyclable at the end of life, to ensure zero landfill waste.

Harrison Spinks is proudly recognized as one of the world's best bed manufacturers and hold numerous Queen's Awards in areas such as Innovation, Sustainability and International Trade.

General Availability Advice

The Mattress & Sleep Company is a family owned and operated business based in Alberta, Canada. We specialize in high-quality bedding, bath and mattresses from Canada, Europe and the USA. Our vast selection makes it impossible to stock everything. For this reason, our website does not offer real-time inventory availability as many of our products are made to order.

Please read the availability details above as we do make an effort to draw attention to products which are typically in stock in our Calgary, Edmonton and Sherwood Park stores and warehouses.

For time-sensitive needs, please give us a call Toll-Free on 1 (877) 750-1212 or Send us a Message and we will be delighted to help.
