Assessed from the specification published by Mattress Man, captured September 2026, and from regular price comparison across our UK retail partners.
If you want a pocket spring mattress with a medium feel from a well-established British maker, this is a reasonable place to start. Medium tension tends to suit back sleepers and most side sleepers, although very heavy sleepers sometimes prefer something firmer. The price asks a lot, from £1,189.15 upwards. Mattressman, currently the one retailer listing it, offers free next day delivery and a 60-night trial on its listing, which gives you a genuine chance to sleep on it at home before committing. Those terms are Mattressman's own, so check them if you buy elsewhere.
Key Features & what's inside

Who's it NOT for?
It's a stretch for tighter budgets, with prices starting at £1,189.15. There's no UK Single in the listed sizes, only an EU Single, so check measurements carefully. And if you like to compare spring counts and layer-by-layer construction before spending this much, the available listing doesn't provide those details.
Harrison Spinks Dream 12500 Medium Mattress
Is the Harrison Spinks Dream 12500 firm or soft?
It's listed as a medium firmness, which means a middle-ground feel: enough give for side sleepers to sink slightly at the shoulder and hip, with enough support for back sleepers. Lightweight sleepers may find it a touch firmer than expected, as is often the way with medium ratings.
What sizes does the Harrison Spinks Dream 12500 come in?
It's available in UK Double, UK King and UK Super King, plus an EU Single. Note there's no standard UK Single in the listed sizes, and EU sizing differs slightly from UK sizing, so measure your bed frame before ordering.
How much does the Harrison Spinks Dream 12500 cost?
Prices range from £1,189 to £2,210 depending on the size you choose, starting at £1,189.15. That's a significant spend, so it's worth taking advantage of any home trial the retailer offers before you commit.
Does the Harrison Spinks Dream 12500 come with a trial?
Mattressman lists a 60-night trial on this mattress, along with free next day delivery, with a handling time of 0-1 days and transit of 1-3 days. These are Mattressman's own terms rather than a Harrison Spinks offer, so they may not apply if you buy from another retailer.
