Assessed from British Bed Company's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
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 from-price of £599 sits at the accessible end for a pocket spring mattress, though larger sizes climb towards £1,003. 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.

Who's it NOT for?
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.

Does the grand duke mattress come with a trial?
Yes, a 60-night trial is offered, so you have around two months to sleep on it at home and decide whether it suits you.
What sizes does the grand duke mattress come in?
It comes in UK Single, Small Double, Double, King and Super King, plus EU Small Single, EU Single, EU Double and EU King. The EU options are a genuine plus if you own a continental bed frame.
How much does the grand duke mattress cost?
Prices range from £599 to £1,003 depending on the size you choose, starting at £599 for the smallest option.
How quickly is the grand duke mattress delivered?
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.
What type of mattress is the grand duke?
It is a pocket spring mattress, which means each spring sits in its own fabric pocket and moves independently. In practice, that gives more tailored support and less motion transfer than an open coil design.
