Arthur Sleep Graphite Arthur Mattress
The Graphite Arthur from Arthur Sleep is a pocket spring mattress, which means the springs are individually wrapped in fabric pockets so they respond to your body separately rather than moving as one unit.

The Graphite Arthur comes in five sizes, from UK Single up to UK Super King. Published detail on this model is thin: the listing we found does not state the depth, spring count or firmness, so it is harder to judge fit than with most mattresses. Mattressman lists a 60-night trial and free next day delivery on its own terms.

Why should you choose this mattress?
Pocket springs are a sensible starting point if you share a bed, since each spring compresses independently and that tends to limit how much of your partner's movement you feel. This sits in accessible territory for a pocket sprung mattress. Buying through Mattressman also brings that retailer's 60-night trial, which gives you a proper stretch of nights to decide rather than a quick showroom lie-down.
Key features & layer details
We’re still collecting information on this mattress. Unfortunately, we don’t have its key features yet.
Best suited for?
Couples
Pocket springs compress independently, which tends to limit how much of your partner's movement you feel when sharing a bed.
Combination sleepers
A 60-night trial gives you plenty of time to see whether the mattress copes with changing positions through the night before committing.
Guest rooms
Five sizes from UK Single up to UK Super King make it easy to match the mattress to a spare room of almost any size.
If you want to compare specifications carefully before buying, this model may frustrate you: no firmness rating, spring count or depth is published, so lightweight or heavier sleepers cannot easily judge suitability in advance.
Save on an earlier or ex-display model
Some retailers still sell the earlier version of this mattress, or ex-display and returned stock at a lower price. These are the sizes where it costs less than the current model's best price.

FAQ's
What sizes does the Arthur Sleep Graphite Arthur mattress come in?
Five UK sizes are available: Single, Small Double, Double, King and Super King.
Does the Arthur Sleep Graphite Arthur mattress come with a trial?
Mattressman lists a 60-night trial. That is the retailer's own offer rather than a manufacturer promise, so check the terms with them directly before you buy.
How quickly can the Graphite Arthur mattress be delivered?
Mattressman lists free next day delivery for this mattress, with a handling time of 0 to 1 days and transit of 1 to 3 days. These are the retailer's delivery terms, so confirm availability for your postcode at checkout.
Is the Arthur Sleep Graphite Arthur a pocket spring mattress?
Yes. It uses pocket springs, meaning each spring sits in its own fabric pocket and moves independently, which helps limit motion transfer between partners. The spring count and construction layers are not published on the listing we found.
