Layer Details
Micro tablet springs
The top layer is made up of 3000 Confonomic micro tablet springs, which sit above the main spring system. This means a more responsive, finely sprung surface over the support beneath.
Pocket spring base
The base layer has 1000 standard pocket springs, forming the lower tier of the 2-tier ErgoZone7 system. It provides the main support, arranged in seven zones to suit different parts of your body.

Key benefits
- Made for typical UK bedrooms: At 135 x 190cm it fits where a UK king would dominate; we suggest a room of at least 2.6m x 2.8m.
- Room for two on 4,000 pocket springs: With 67.5cm each, two sharers get individual spring support across the full width rather than rolling into a shared dip.
- Pillowtop comfort at a shareable size: The pillowtop finish softens the medium firm feel for both sleepers, which matters more in a size built for sharing.
- Space for bedside tables: A 135cm-wide bed usually leaves walkway and table space on both sides in an average room, which a UK king often doesn't.
- Bedding is easy and cheap to find: Double sheets and a 200 x 200cm double duvet are stocked everywhere, so dressing the bed costs less than the larger sizes.
This size suits you if...
You share the bed most nights and your room sits around the typical UK size, where a bigger mattress would crowd out the wardrobe and drawers. It also suits you if you sleep alone but like space to stretch, perhaps with a dog or cat claiming one corner, or if you're setting up a guest room that visiting couples will use.
Consider another size if...
You and your partner both toss and turn, because 67.5cm each can feel snug. We'd recommend the UK king instead: it's 15cm wider and 10cm longer, giving 75cm each, and needs a room of at least 2.7m x 2.9m.

FAQ's
Is the Millbrook Allure Pocket 4000 in a double big enough for a couple?
For most couples, yes. The UK double gives 67.5cm of width each, and with 4,000 pocket springs across the mattress you each get support that responds to your own weight rather than your partner's movement. If either of you is tall or a restless sleeper, the UK king's extra 15cm of width and 10cm of length is worth considering.
What room size do I need for the Millbrook Allure in a UK double?
We suggest at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That allows walking space at the foot and sides, and in most rooms leaves enough width for bedside tables on both sides, something a UK king can rule out in a smaller room.
Should I get the Millbrook Allure in a UK double or a UK king?
It comes down to your room. The UK king is 15cm wider and 10cm longer, giving sharers 75cm each against the UK double's 67.5cm, but it needs a room of at least 2.7m x 2.9m. If yours is smaller, or you want furniture either side of the bed, the UK double is the sensible pick.
What bedding fits this mattress in a double?
Standard UK double sheets fit the 135 x 190cm footprint, paired with a 200 x 200cm double duvet. The pillowtop adds height, so if the fitted sheet feels tight, look for a deep-fitted double, which most bedding ranges stock at every price point.
Will a UK double Millbrook Allure fit up narrow stairs?
A pocket-sprung pillowtop mattress can't be rolled or folded, so the full 135 x 190cm has to turn every corner on the way up. Measure any tight landings or turning stairs before ordering, particularly in older terraces and compact new builds, and check the retailer's delivery access policy through the listings on this page.
