Layer Details
Pillowtop
A sumptuous tufted pillowtop with layers of British wool. This is what gives the mattress its soft, sink-in first impression.
Silk, wool, cashmere and alpaca layer
An additional layer of silk, wool, cashmere and alpaca, which means the comfort layers breathe well and regulate temperature rather than trapping heat.
Sustainable fresh fibres
British wool layered with sustainable fresh fibres. This adds cushioning depth between the natural fillings and the springs.
Pocket springs
2000 zoned pocket springs with an additional 1000 mini springs. The zoning means firmer support under heavier areas like your hips, while the mini springs fine-tune the surface response.

Key benefits
- The traditional couples' size: At 135cm wide you get 67.5cm each for two people sharing, which is the long-established standard for UK couples.
- Zoned springs work for two: The 2000 zoned pocket springs support each sleeper's hips independently, which means a lighter partner isn't dragged into the dip a heavier one makes.
- Breathable for shared warmth: Two bodies generate more heat than one, and the wool, silk, cashmere and alpaca fillings let that warmth escape rather than trap it.
- Fits rooms a UK king would crowd: Allow 2.6m x 2.8m and you'll still have space for bedside tables on both sides, something the UK king often rules out in older homes.
- Easy to dress: Standard double sheets and a 200 x 200cm double duvet are stocked everywhere, so replacing bedding is cheap and simple.
This size suits you if...
You share the bed most nights and want a soft, cushioned surface without giving your bedroom over to a UK king, or you sleep alone and want proper space to stretch out, perhaps with a cat or dog claiming their usual corner. It also suits a guest room that regularly hosts visiting couples, where a plush pillowtop makes people feel looked after.
Consider another size if...
You and your partner both like room to sprawl, or one of you is a restless sleeper. The UK king is 15cm wider and 10cm longer than the UK double, and we'd recommend it if your room allows at least 2.7m x 2.9m.

FAQ's
Is the Milldale 3000 in a UK double wide enough for two people?
For most couples, yes. The UK double gives 67.5cm each for two people sharing, and the zoned pocket springs respond to each sleeper separately, so you feel less of your partner's movement. Taller or broader couples may find it a little snug, in which case the UK king adds 15cm of width and 10cm of length.
What room size do I need for a double Milldale 3000 with bedside tables?
We suggest at least 2.6m x 2.8m for a UK double, with around 3m x 3m the comfortable norm. That minimum should still leave enough clearance for bedside tables on both sides in most rooms, which is one of the main reasons couples in typical UK bedrooms choose a double over a UK king.
Will a UK double Milldale 3000 fit up a narrow staircase?
Silentnight doesn't publish a boxed size for this mattress, so check with the retailer before ordering. It's a 32.5cm deep pillowtop mattress at 135 x 190cm, so it needs some flexing round turning stairs in older terraces or tight new build landings. Pocket sprung mattresses bend less readily than foam, so measure your tightest turn first.
Does a soft pillowtop suit couples of different weights in a double?
Better than you might expect. The 2000 zoned springs give firmer support under heavier areas like the hips, and the 1000 mini springs fine-tune the surface, so each side responds to the person on it. That said, this is the Softer build, and a noticeably heavier partner may still sink further into the pillowtop than a lighter one.
Should a solo sleeper get the Milldale 3000 in a double or a single?
If the room allows it, the UK double is the more comfortable choice: it's 45cm wider than the UK single at the same length, which means space to spread out or share with a pet. The UK single needs a room of at least 2.1m x 2.8m, so it's the sensible pick for a compact second bedroom or first flat.
