Why should you choose this mattress?
The springs sit in their own cloth sleeves and work independently, which means the mattress minimises partner disturbance if one of you tosses and turns. The foam and fibre layers add cushioning over the springs, so the medium-firm support doesn't feel bare. The white fibre filling is described as hypo-allergenic, which may appeal if you're sensitive to fillings. It's also double sided, so you can flip and rotate it to spread wear. It suits most back sleepers and many combination sleepers, although very light side sleepers may want something softer.
Key features & layer details
Pocket springs
Springs housed in their own cloth sleeves, smaller in diameter than open coils and independent of their neighbours. That means they respond separately, which cuts the movement you feel from a partner.
High-density advanced comfort foam
A high-density foam that works with the springs to give a medium to firm support. It adds body-contouring without making the mattress feel soft.
White fibre comfort layers
Generous white fibre layers, described as hypo-allergenic. They add a cushioned surface feel and may suit you if you're sensitive to fillings.
Advanced reflex foam
A deep layer of advanced reflex foam beneath the white fibre. It adds a supportive base to the comfort layers above.

Best suited for?
Back sleepers
The medium-firm feel and pocket springs give a supportive surface, with foam and fibre layers on top so it doesn't feel bare underneath you.
Combination sleepers
Medium-firm support from the pocket springs and comfort foam suits people who change position, and the cushioned fibre layers keep each position comfortable.
Couples
Each spring sits in its own cloth sleeve and works independently, which means less movement carries across the bed when one of you tosses and turns.
Allergy sufferers
The white fibre comfort layers are described as hypo-allergenic, which may appeal if you are sensitive to fillings and want a gentler sleep surface.
If you prefer sleeping on a soft mattress, this might not be the best choice. It's rated medium firm, and lighter side sleepers may find it a little unyielding at the shoulders and hips. No spring count is published, so you can't judge the support that way. The fault guarantee is also only one year.
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 Highgrove Ottawa Pocket 1000?
It's rated medium firm, and the retailer describes the support as medium to firm. That suits most back sleepers, although lighter side sleepers may find it a little firm.
What sizes does the Highgrove Ottawa Pocket 1000 come in?
It comes in a UK small single, UK single, UK long single, UK small double, UK double, UK king and UK super king. The UK king is 150 x 200cm and the UK super king is 180 x 200cm.
How deep is the Highgrove Ottawa Pocket 1000?
It's 29cm deep, according to the retailer's dimensions. That's enough room for the pocket springs plus the foam and fibre comfort layers above them.
Is the Highgrove Ottawa Pocket 1000 good for couples?
Yes, in most cases. The pocket springs are independent of each other and are described as minimising partner disturbance. Couples who want a softer feel may still find the medium-firm surface too firm.
Can you flip the Highgrove Ottawa Pocket 1000?
Yes, it's double sided, so you can both flip and rotate it. That helps spread wear more evenly over time, which is useful if you sleep in the same spot each night.
