Rest Assured Northington 2000 Pocket Natural Double Mattress
The Rest Assured Northington 2000 Pocket Natural Mattress is a firm pocket spring mattress with a run of natural fillings: silk, cashmere and traceable British wool sit over 2,000 pocket springs, which means each spring moves independently and responds to your body rather than the whole bed shifting when your partner does.

Layer Details
Silk
A light, soft top comfort layer, which means the first thing you feel is gentle rather than the firm springs beneath. It adds a touch of luxury without changing the overall firm support.
Cashmere
A rare filling that's softer and finer than wool, typically reserved for higher quality mattresses. It sits just under the silk to cushion the sleeping surface.
Authentic Traceable British Wool
Wool from British Cheviot sheep, fully traceable from farm to shop, with a naturally strong yet soft fleece. It gives a natural bounce and helps regulate your temperature, so you're less likely to overheat.
2000 Pocket Springs
Each spring is sewn into its own fabric pocket, which means they work independently and contour to your body for better pressure relief. This also limits motion transfer, useful if you share the bed.

Key benefits
- Shared bed, modest footprint: At 135 x 190cm, the UK double gives two sleepers a shared bed while leaving floor space in rooms where a UK king would crowd the walls.
- Less disturbance on a narrower bed: The 2,000 pocket springs move independently, which means a partner turning over 67.5cm away is less likely to jolt you awake.
- Firm support for two: The firm spring core holds each sleeper up on their own side, so you're less likely to roll towards the middle of a shared UK double.
- Cooler for couples: The British wool layer helps regulate temperature, a real help when two bodies share a UK double and the bed warms up through the night.
- Easy bedding: Double sheets are stocked almost everywhere, and a 200 x 200cm double duvet completes the bed without any hunting around.
This size suits you if...
You share a bed with a partner in a standard-sized British bedroom and want space for bedside tables on both sides, or you're furnishing a spare room where visiting couples need a proper shared bed with firm support.
Consider another size if...
You both want more than 67.5cm each, or one of you is tall. We'd recommend the UK king instead, which gives 75cm each and 10cm extra length; allow at least 2.7m x 2.9m.

FAQ's
Will a Northington 2000 UK double fit with bedside tables on both sides?
We suggest a room of at least 2.6m x 2.8m for a UK double, with around 3m x 3m the comfortable norm. In that 3m x 3m space you should be able to fit a bedside table on each side and still walk around the bed. In a tighter room, measure your furniture before you commit.
How much room does each person get on the Northington 2000 double?
Two people sharing a UK double get 67.5cm each. That's snug for couples who sprawl, although the independent pocket springs help by limiting movement across the bed. If you want more room, the UK king gives 75cm each, and we suggest at least 2.7m x 2.9m for the UK king.
Is the Rest Assured Northington 2000 UK double long enough if you're tall?
The UK double is 190cm long, or 6ft 3in. If either of you is close to that height, your feet may reach the edge. The UK king is 10cm longer, so it's the better choice for tall sleepers who have the floor space. We suggest at least 2.7m x 2.9m for a UK king.
Is the Northington 2000 double a good choice for a guest room?
Yes, if couples stay with you. A UK double sleeps two without taking over a spare room, and the firm support suits most back and front sleepers. The firmness is the one catch: lightweight guests who sleep on their side may find it a little hard on the shoulders and hips.
Is the Northington 2000 UK double too big for one person?
Not usually. The UK double is 45cm wider than the UK single, which gives a solo sleeper room to stretch out, or to share with a dog or cat that claims a corner. If floor space is tight and you sleep alone, we suggest at least 2.1m x 2.8m for the UK single.
