Layer Details
Pillow top
An extra layer of comfort on the surface for a more cushioned feel. It softens the first impression of the mattress without changing its firm rating.
Comfort layer
A soft blend of Hampshire wool and English spun cotton. These natural fibres add cushioning between you and the springs.
Sprung core
1000 individually pocketed springs, each encased in a cloth pocket. This gives the firm support the mattress is rated for.

Key benefits
- More room each than a double: Moving from a UK double gives you 7.5cm more width each, which means a little more space to turn over without nudging your partner.
- Length for taller partners: At 200cm long, the UK king is 10cm longer than the UK double, so a partner over six foot is less likely to have feet hanging off the end.
- Steadier when one of you gets up early: The 1000 springs sit in individual cloth pockets, which means one partner leaving the bed before dawn should disturb the other less than a connected spring unit would.
- Firm edges across the wider surface: A double metal rod border reinforces the edge, so sitting on the side to get in or out should feel more stable, which helps after injury or surgery.
- Space for pillows and repositioning: In pregnancy and the months after, the extra width leaves room for a support pillow while the firm core keeps your spine level.
This size suits you if...
You share the bed every night and keep waking each other on a double, or one of you is over six foot and the extra length matters more than the width. It also suits couples on different schedules who want a little more distance between them, provided you both like a firm feel.
Consider another size if...
Your bedroom is smaller than our suggested 2.7m x 2.9m once wardrobes are in. We'd recommend the UK double instead, which needs at least 2.6m x 2.8m.

FAQ's
Is the Millbrook Wool Ortho 1000 Pillow Top UK king big enough for two people?
For most couples, yes. The UK king gives you 75cm each, which is 7.5cm more each than the UK double. If you also share with a dog that sprawls, or you both sleep starfished, the UK super king's 90cm each may suit you better, though it needs at least 3m x 2.9m of room.
What size room do I need for a Millbrook Ortho 1000 king size mattress?
We suggest allowing at least 2.7m x 2.9m for the UK king, with 3.2m x 3.2m giving comfortable space to walk around and open drawers. New build master bedrooms can feel smaller once fitted wardrobes go in, so measure from the wardrobe doors rather than the bare wall.
Will a 6ft partner fit on the Millbrook Wool Ortho 1000 Pillow Top king?
The UK king is 200cm long, which is 10cm longer than the UK double and the UK small double. For anyone around six foot, that extra length usually means feet stay on the mattress rather than resting on the footboard. The UK super king is the same length, so sizing up adds width only.
Should we get the UK king or UK super king in the Millbrook Ortho 1000?
Both are 200cm long, so choose on width and room. The UK king is 30cm narrower, giving 15cm less each, but it needs less floor space. If partner disturbance is the main problem and your room allows at least 3m x 2.9m, the UK super king gives more separation.
What bedding fits a Millbrook Wool Ortho 1000 king size mattress?
Standard UK king sheets fit the 150 x 200cm surface, and a 230 x 220cm king duvet covers it. As the mattress is 29cm deep, choose fitted sheets with deep pockets so the corners stay put over the pillow top.
