Assessed from the specification published by Mattress Man, captured September 2026, and from regular price comparison across our UK retail partners.
A medium feel suits most sleepers, sitting between the softer surface side sleepers tend to prefer and the firmer support back sleepers often want. If you sleep in a mix of positions, that middle ground is usually the safest bet. Pocket springs also mean less motion transfer, so a restless partner is less likely to wake you. Buying through Mattressman gets you a 60-night trial and free next day delivery, though be clear these are that retailer's own terms rather than a Harrison Spinks promise, so they won't necessarily apply elsewhere. Yes, the starting price of £1,019.15 is a serious outlay, but Harrison Spinks is a heritage manufacturer, and you're paying for that provenance.
Key Features & what's inside
Awaiting up to date specifications. Please check back later.
Who's it NOT for?
If you're a lightweight side sleeper, a medium feel may be slightly too firm to let your shoulder and hip sink in properly. It's also a poor fit for tight budgets, with prices starting at £1,019.15. And if you need full construction specs before committing, the listing simply doesn't provide them.
Harrison Spinks Sanctuary 9500 Medium Mattress
How firm is the Harrison Spinks Sanctuary 9500?
It's listed as medium, the middle of the firmness scale. In practice that means a balanced feel: enough give for side sleeping, enough support for your back. Lightweight side sleepers may find it a little firm, while heavier sleepers who need a very supportive surface might prefer something firmer.
What sizes does the Sanctuary 9500 come in?
Four sizes are available: UK Double, UK King, UK Super King and EU Single. Note there's no standard UK Single, so if you need one for a British single bed frame, this isn't the mattress for you. Prices range from £1,019 to £1,870 depending on the size you choose.
Does the Harrison Spinks Sanctuary 9500 come with a trial period?
Mattressman lists a 60-night trial with this mattress. That's the retailer's own offer rather than a Harrison Spinks guarantee, so it applies when you buy from Mattressman and may not be available through other sellers. Always check the trial terms with whichever retailer you order from.
How much does the Sanctuary 9500 cost?
Prices run from £1,019 to £1,870 depending on size, with the cheapest option starting at £1,019.15. That's a premium price, but it reflects Harrison Spinks' position as a heritage British bedmaker rather than a budget bed-in-a-box brand.
How quickly can the Sanctuary 9500 be delivered?
Mattressman offers free next day delivery on this mattress. That's the retailer's own service, so delivery speed and cost may differ if you buy through another seller.
