Why should I buy a Stuart James mattress?

Stuart James was created by a team with over 30 years of experience in the bedding industry. The main goal was to create a high quality range of mattresses that can stand the test of time, provide a long lasting comfort and ensure the highest of standards are met whilst value for money is provided. Our team has a lot of retail experience and has dealt with the issues that come from other manufactures. Our mattresses cover all the faults we have found throughout the years from edge support to ensuring the luxury layers we put in our mattresses are settlement proof.

What are vanadium steel springs?

Our calico springs are made in the U.K. using the finest vanadium steel springs, which are calico encased. A standard spring is encased with a polyprop cover, where as calico is 100% cotton, even the thread. This allows the spring to be far more flexible, durable and provide a far more responsive support.

What does GSM mean?

We refer to GSM when we talk about the amount of layers we put in our mattresses. We want you to know exactly what is in the mattress and what you are paying for. GSM stands for grams per square metre. For example, in our Regal Queen mattress you will find 1200g Laywool, 250g Pashmina, 200g Peruvian White Alpaca, 1000g Alpaca, 1000g Wool/Cotton. This is a total of 3650grams but that’s how many grams is in every square metre of the mattress. All our mattresses are also completely reversible, so the comfort is exactly the same on both sides – that’s a lot of filling!
