Assessed from the specification published by Mattress Man, captured September 2026, and from regular price comparison across our UK retail partners.
The main draw here is the spring count. With 3,000 pocket springs, the Royal Arthur offers more precise contouring than mattresses with fewer, larger springs, which means less motion transfer if you share a bed and support that adjusts to your hips and shoulders separately. The firm tension will appeal if you sleep on your back or front, or simply prefer a firmer bed. From £599 it sits at a reasonable price for this spring count, with limited published detail on the exact construction. If you buy through Mattressman, they list a 60-night trial and free next day delivery, plus old mattress removal as one of their services.
Key Features & what's inside

Who's it NOT for?
This is a firm tension mattress, so lightweight side sleepers may find it a little too unyielding at the shoulder and hip. If you want detailed information about foams, fillings or mattress depth before buying, the published specs here are slim: beyond pocket springs, the materials aren't itemised.

How firm is the Arthur Sleep Royal Arthur mattress?
It's listed as a firm tension. That generally suits back and front sleepers, and heavier builds who need extra pushback. Lightweight side sleepers may find it slightly too firm for comfortable pressure relief at the shoulder.
How many springs does the Royal Arthur mattress have?
It contains 3,000 pocket springs. Each spring is sewn into its own fabric pocket and compresses independently, which means the mattress responds to your body shape and limits movement transferring across the bed to a partner.
Does the Royal Arthur mattress come with a trial period?
Mattressman, the retailer currently stocking it, lists a 60-night trial. That's the retailer's own offer rather than a manufacturer guarantee, so check the terms at the point of purchase before you buy.
What sizes does the Royal Arthur mattress come in?
It's available in UK Single, Double, King and Super King, with prices ranging from £599 to £892 depending on the size you choose.
How quickly can the Royal Arthur mattress be delivered?
Mattressman lists free next day delivery, with a handling time of 0 to 1 day and transit of 1 to 3 days. They also mention old mattress removal as a service. These are the retailer's terms, not the brand's.
