Harrison Spinks Dream 12500 Medium Mattress

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. Mattressman 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.

Back sleepers
The medium firmness gives a balance of support and give, which tends to suit people who spend the night lying on their backs.

Side sleepers
Medium tension tends to work for most side sleepers, since the pocket spring feel gives a little at the shoulder and hip.

Couples
Double, King and Super King sizes give two people room to spread out, with a medium feel that suits many different sleeping positions.

European bed frames
An EU Single size is listed alongside the larger sizes, so it can suit a continental frame where a UK Single would not fit.

Its starting price is a stretch for tighter budgets. 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 buying, the available listing doesn't provide those details.

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?

It depends on the size you choose, and the price table on this page shows the current price for each size. It'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.
