Harrison Spinks Emerald 16500 Pocket Mattress (Firmer Feel)

Assessed from the product page published by Mattress Online, captured September 2026, and from regular price comparison across our UK retail partners.

This is a firm pocket spring mattress, which means individual springs respond to your body independently rather than moving as one unit, so you and a partner are less likely to disturb each other. The firm feel suits back and front sleepers who want to stay on top of the mattress rather than sink into it, and heavier sleepers who find softer models give way too quickly. Sizes run from UK Single to UK Super King. Yes, the starting price is a serious outlay, but pocket spring construction at this level is generally built for the long haul, and it's listed with a 5 year guarantee.

Back sleepers
The firm feel keeps you on top of the mattress rather than sinking in, which gives a supportive, level surface when lying on your back.

Front sleepers
A firm surface stops your hips dropping too far into the mattress, so you stay on top of it rather than sinking in.

Heavier sleepers
Firm pocket springs resist giving way too quickly, which suits heavier sleepers who find softer models sink down and lose their support.

Couples
Individual pocket springs respond to each body independently rather than moving as one unit, so one partner is less likely to disturb the other.

If you're a lightweight side sleeper, a firm mattress like this may not give enough at the shoulder and hip, which can mean pressure points rather than comfort. It's also a poor fit for tight budgets. Softer variants of this model exist, so check you're ordering the right one.
