The Grand Duke's size range is unusually broad: alongside the standard UK sizes from Single up to Super King, it also comes in EU sizes, which is handy if you have a continental bed frame. It carries a 4.7 rating from 149 reviews on mattressman.co.uk, and there is a 60-night trial plus free next day delivery. One downside: published details on the internal construction are thin, so you are buying more on reputation and reviews than on a spec sheet.

Why should you choose this mattress?
If you want a traditional pocket sprung feel with room to try it at home, the Grand Duke makes a reasonable case. The 60-night trial gives you two months to decide, and free next day delivery means you are not waiting weeks for it to arrive. The starting price sits at the accessible end for a pocket spring mattress, though larger sizes cost more. It also suits shoppers with EU-sized bed frames, who are often poorly served by UK brands. The lack of published spring counts and layer details is frustrating for a careful buyer, but the 4.7 average across 149 reviews suggests owners are broadly happy with what turns up.
Key features & layer details
We’re still collecting information on this mattress. Unfortunately, we don’t have its key features yet.
Best suited for?
European bed frames
EU sizes sit alongside the standard UK range, so owners of a continental frame can find a mattress that fits without hunting around.
Budget buyers
The starting size sits at the accessible end for a pocket spring mattress, which keeps the entry cost down for smaller beds.
Combination sleepers
A traditional pocket sprung feel suits people who shift position overnight, and the 60-night trial gives time to check it at home.
Couples
Sizes run up to Super King, which gives two people plenty of room, and the trial lets you both decide over two months.
If you like to compare spring counts, depths and firmness ratings before spending your money, the sparse published specification here will frustrate you. It is also not the mattress for anyone set on an all-foam or hybrid feel, as this is a traditional pocket spring design.
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.

Free next day delivery is offered, with a handling time of 0 to 1 days and transit of 1 to 3 days, so it should be with you quickly.
