At 23cm deep, the Vispring Kingsbridge Extra Firm has a slimmer profile than many luxury mattresses, though depth alone says little about quality. It's available in UK King and UK Super King. It is serious money, and this tension suits a specific sleeper: typically heavier people, or those who genuinely prefer a very solid feel. If you sleep on your side or weigh less, an extra firm surface may feel unforgiving rather than supportive.

Why should you choose this mattress?
Choose this one if you know you want a genuinely firm sleeping surface from a pocket spring construction. Pocket springs move independently, which means the mattress can respond to each sleeper separately rather than tilting you both towards the middle. The extra firm tension keeps you resting on the surface rather than sinking into it, something heavier sleepers and committed back sleepers often prefer. The price puts it firmly in the luxury bracket, and it's only made in UK King and UK Super King, so smaller bedrooms are out. But if a solid, supportive feel in a large size is exactly what you're after, it fits the brief.
Key features & layer details
We’re still collecting information on this mattress. Unfortunately, we don’t have its key features yet.
Best suited for?
Heavier sleepers
The extra firm tension keeps you resting on the surface rather than sinking in, which heavier sleepers often prefer for a solid, supportive feel.
Back sleepers
Committed back sleepers often like the extra firm tension, as it keeps you on top of the mattress instead of letting you sink into it.
Couples
Pocket springs move independently, which means the mattress responds to each person separately rather than tilting you both towards the middle, and it comes in King and Super King.
Lightweight sleepers and dedicated side sleepers should look elsewhere: extra firm tension can press uncomfortably at the shoulder and hip rather than letting them settle in. It's also unsuitable if you need a Single or Double, as only UK King and UK Super King are made, or if the starting price stretches your budget.
Save on an earlier or ex-display model
Some retailers still sell the earlier version of this mattress, or ex-display and returned stock at a lower price. These are the sizes where it costs less than the current model's best price.

FAQ's
How firm is the Vispring Kingsbridge Extra Firm mattress?
It's an extra firm tension, the firmest option in the Kingsbridge range. Expect a very solid surface with minimal sink, which tends to suit heavier sleepers and those who prefer sleeping on top of a mattress rather than into it.
What sizes does the Vispring Kingsbridge Extra Firm come in?
It's available in two sizes: UK King and UK Super King. If you need a Single, Double or a European size, this particular listing won't cover you.
How much does the Vispring Kingsbridge Extra Firm cost?
It depends on the size you choose, and the price table on this page shows the current price for each size. It sits well into luxury territory, so it's a purchase to weigh carefully against how much you value a traditional pocket spring build in this tension.
How deep is the Vispring Kingsbridge Extra Firm mattress?
It measures 23cm deep. That's slightly shallower than some luxury mattresses, which can actually be a practical plus: standard fitted sheets will fit without a struggle.
