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.

Key benefits
- Leaves floor space for everything else: At 90cm wide, a UK single leaves room for a wardrobe and a desk in a small bedroom, and we suggest a room of at least 2.1m x 2.8m.
- Two beds where one won't do: Two UK singles with a walkway between them suit siblings sharing a room, or a guest room that needs to sleep two friends apart.
- Cushioning over the springs: Foam and white fibre layers sit above the pocket springs, which means a teenager or adult guest gets medium-firm support without a bare, springy surface.
- Fibre filling for sensitive sleepers: The white fibre layers are described as hypo-allergenic, which may reassure you if your child reacts to some fillings.
- Simpler to get into awkward rooms: It comes vacuum packed in a box, so carrying a UK single up narrow stairs to a loft conversion or student room is far less of a struggle.
This size suits you if...
You're furnishing a child's or teenager's bedroom where a desk and storage need floor space too, you're kitting out a student room or spare room for one person, or you want two separate beds in a shared or guest room.
Consider another size if...
Your child is already outgrowing a single, or you're an adult who likes room to spread out. We'd recommend the UK small double instead: 30cm wider, same length, and we suggest at least 2.4m x 2.8m for it.

FAQ's
Will the Highgrove Ottawa Pocket 1000 single fit a bunk bed?
It may, but at 29cm deep it is deeper than some raised frames allow, because the safety rail needs to sit comfortably above the mattress surface. Check the maximum mattress depth your bunk, cabin bed or mid sleeper specifies before you buy.
What size is the Highgrove Ottawa Pocket 1000 UK single in feet?
It measures 3ft x 6ft 3in, or 90 x 190cm, the standard UK single footprint. A standard single bed frame takes it, and standard single sheets and a single duvet (135 x 200cm) fit.
How big a room do I need for a UK single Highgrove Ottawa?
We suggest allowing at least 2.1m x 2.8m. That leaves space to get round the bed and open a wardrobe in a small bedroom, or in a spare room that also works as a home office.
Is a UK single Highgrove Ottawa Pocket 1000 long enough for a teenager?
For most teenagers, yes, and the medium-firm feel suits back and combination sleepers. If your teenager is very tall, the UK king is 10cm longer than the UK single, although we suggest at least 2.7m x 2.9m of floor space for the UK king.
How much narrower is a single than a double in the Highgrove Ottawa?
The UK single is 45cm narrower than the UK double and the same length. The UK double gives 67.5cm each for two sharing, and we suggest at least 2.6m x 2.8m for it, so it's the better step up if a guest room ever needs to sleep a couple.
