Our Goal: The Most Comfortable Double Size Mattress In Ireland.

Our Double Mattress Isn’t Made From a Piece of Heaven, but It Does Feel Like It Is.

Double mattresses are one of Ireland’s favourite mattress sizes. This is because doubles are just right for one to two people. The Spinery’s Fitzwilliam double is slightly smaller than our king and super king mattress, but it delivers the same quality sleep as its larger brothers and sisters.

Our Fitzwilliam Mattress uses only quality materials.


Our double size mattress is crafted using the highest quality foams and fabrics. Our double size mattress is made from 100% natural and plant-based materials which means it’s safe for you and the environment.
