Assessed from the specification published by Mattress Man, captured September 2026, and from regular price comparison across our UK retail partners.
Pocket springs move independently of one another, which means less motion transfer when a partner shifts about and support that follows the shape of your body rather than pushing back as one unit. Harrison Spinks is the maker here, and the price spread of £699 to £1,144 sits it in mid-range territory for a pocket sprung mattress. Buying through Mattressman brings a 60-night trial, free next day delivery and old mattress removal, though these are the retailer's terms rather than the brand's, so check them at the point of purchase. The published product detail is sparse, so this suits buyers comfortable asking a few questions before committing.
Key Features & what's inside

Who's it NOT for?
If you need a UK Single, you're out of luck: the sizes run UK Double, King and Super King, with an EU Single as the only smaller option. It's also not ideal if you want full transparency on fillings, firmness and spring counts before buying, as that detail isn't currently published.

How much does the Harrison Spinks Extra Plush 3000 cost?
Prices run from £699 to £1,144 depending on the size you choose, starting at £699.00. That places it in the mid-range for a pocket spring mattress, though as ever the larger sizes account for the top end of that spread.
What sizes does the Harrison Spinks Extra Plush 3000 come in?
Four sizes: UK Double, UK King, UK Super King and an EU Single. There's no standard UK Single, so if you need one for a child's room or guest bed, this isn't the model for you.
Does the Harrison Spinks Extra Plush 3000 come with a trial period?
Mattressman, currently the only retailer stocking it, lists a 60-night trial. This is the retailer's own offer rather than a manufacturer guarantee, so confirm the terms when you order, particularly around returns conditions.
How quickly is the Harrison Spinks Extra Plush 3000 delivered?
Mattressman offers free next day delivery on this mattress, with a handling time of 0 to 1 day and transit of 1 to 3 days. The retailer also mentions old mattress removal as a service, which saves you a trip to the tip.
