Arthur Sleep Copper Arthur Mattress

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 copper-infused cover paired with a pocket spring core at a fairly accessible price point. Medium firm suits most sleepers, particularly back and combination sleepers who want support without a rigid feel, although lightweight side sleepers may find it slightly too firm at the shoulder and hip. Across 69 reviews on Mattressman, it holds a 4.9 rating, which is a strong showing, from a modest number of buyers. If you buy through Mattressman, their 60-night trial gives you a proper stretch of time to test it at home.

Back sleepers
Medium firm feel gives steady support without a rigid edge, which means your spine stays comfortably level while you lie flat.

Combination sleepers
A pocket spring build feels springy and responsive, which means changing position through the night takes little effort and the surface moves with you.

Couples
Pocket springs move independently, so you are less likely to feel a partner shifting about in the night, and it comes in sizes up to Super King.

Warm sleepers
An open pocket spring core paired with a copper-infused cover suits those who want a springy feel rather than a dense foam one.

If you prefer a soft, sink-in feel, this medium firm build probably isn't for you. Spec-focused buyers should note that depth, spring count and layer details aren't published, so you're buying somewhat on trust. And if you want memory foam contouring, a pocket spring mattress like this feels springier and more responsive instead.

Is the Arthur Sleep Copper Arthur mattress firm or soft?

It's listed as medium firm, which sits towards the supportive end without being hard. That tends to suit back sleepers and heavier side sleepers well. Lighter side sleepers may find it a little too firm for comfortable pressure relief at the shoulder.

Does the Copper Arthur mattress come with a trial period?

Mattressman lists a 60-night sleep trial. That's the retailer's own offer rather than a manufacturer guarantee, so if you buy elsewhere the terms may differ. Always check before ordering.

What sizes does the Arthur Sleep Copper Arthur come in?

Five UK sizes: Single, Small Double, Double, King and Super King.

What is the Copper Arthur mattress made of?

It's a pocket spring mattress with copper-infused materials and a copper fabric cover. Pocket springs move independently, which means better isolation of movement between partners. The retailer listing doesn't publish depth, spring count or a full layer breakdown, so finer construction details aren't available.

How quickly is the Copper Arthur mattress delivered?

Mattressman lists free next day delivery, with a handling time of 0 to 1 day and transit of 1 to 3 days. Those are the retailer's delivery terms, so timings could differ if you buy the mattress elsewhere.
