Ashdown Mattresses Details

Add a touch of luxurious comfort to your sleep sanctuary with our Harrison Spinks Ashdown king-size mattress, offering quality craftsmanship and responsibly sourced fillings.

The no-turn mattress is made-to-order by expert bedmakers and features 3,250 high-density springs to offer pressure relief and comfort. The Cortec™ Quad springs move independently to provide targeted support and excellent airflow for the ultimate in temperature control, while the high-density springs contour the body for a restful night’s sleep.

The mattress is filled with responsibly sourced materials, including hemp and flax from the Harrison Spinks farm in Yorkshire, cotton, and local wool that supports Yorkshire farmers. Ashdown is hand-tufted to ensure the naturally breathable fibres are held securely in place.

Choose from regular or firmer tension options depending on how you sleep, with both providing just the right level of comfort. The mattress is finished with a Fabrisafe™ sleeping surface that’s a wool viscose blend made in-house on Harrison Spinks’ own looms.

Our mattresses are fully compliant with UK Flammability Standards BS7177

Will It Fit?

Choosing the right piece of furniture for your home is a big decision. Not only does it need to look good and do the job it was made to do, but it also needs to fit.

To fit with your interior style, to fit with your home needs, and most importantly, to fit with the dimensions of your room. If the piece of furniture is near a doorway, which way does the door open? Is the item going to be restricting the route in and out of the room? Is there a radiator on the wall, or a windowsill jutting out that you need to factor in when measuring the item’s height?

Check what you can fit comfortably within your room by looking at the furniture measurements. You can find them in the Dimensions & Assembly section. Note them down and get busy with your tape measure.

The final important measurement to mention, is to ensure your new piece of furniture can fit through your front door when it gets delivered! Most items arrive assembled and boxed. The packaged item dimensions can also be found in the Packaging & Assembly section. Download our Will It Fit PDF, and follow our guide to a smooth furniture delivery.
