Layer Details
- MemorySense Memory Foam. A memory foam comfort layer that moulds to your body, which means pressure builds more slowly at your hips and shoulders as you settle. It's designed to soothe pressure points and ease aches and pains.
- PostureTech Core Support Springs. A spring system using unique shapes and varied tensions, which means firmer support where your body is heavier and gentler give elsewhere. The result is full-body support with pressure relief rather than a uniformly hard base.

- Room to share, space to live: At 135cm wide the double leaves most rooms with space for bedside tables on both sides, which a UK king often takes away.
- 67.5cm each for couples: Two people sharing get 67.5cm of width apiece, enough for most couples, although restless sleepers may prefer the extra 15cm a UK king adds.
- Firm support across the full width: The PostureTech springs vary their tension across the mattress, which means both sleepers get support matched to their weight rather than a uniform feel.
- Memory foam that suits sharers: The MemorySense layer absorbs movement as it moulds, so one person settling in slightly later is less likely to wake the other.
- Manageable to move in: At 25cm deep and double width, this size is easier to steer round the turning stairs of an older terrace than a king would be.
- Bedding is everywhere: Standard double sheets and duvets fit, stocked at every price point, which makes replacing worn bedding cheap and simple.
This size suits you if...
You share the bed most nights and your room sits around the typical UK bedroom size, where a UK king would crowd the walkways. It also suits a solo sleeper who wants space to stretch, or perhaps to share with a dog or cat that claims a corner, and anyone furnishing a guest room where visiting couples will stay.
Consider another size if...
You and your partner both move about at night and the room can take something wider. The UK king gives you 15cm more width and 10cm more length; we suggest at least 2.7m x 2.9m for it.

Is the Sealy Eaglesfield double big enough for two adults?
For most couples, yes. The UK double gives 67.5cm each for two people sharing, and the MemorySense foam layer softens movement transfer between you. If either of you is broad-shouldered or a restless sleeper, the UK king's extra 15cm of width may be a better long-term buy, provided your room allows it.
What room size do I need for the Eaglesfield in a UK double?
We suggest at least 2.6m x 2.8m for a UK double. That allows you to walk round the bed and open drawers without shuffling sideways. In a room that size you should also fit bedside tables on both sides, something a UK king in the same room would make a squeeze.
Should I choose the Eaglesfield in a double or a king?
It comes down to your room. The UK double is 15cm narrower and 10cm shorter than the UK king, so it suits typical UK bedrooms where a king would dominate. If you're both over about six feet tall or you sleep restlessly, and the room measures at least 2.7m x 2.9m, the UK king is the more comfortable choice.
Will the double Eaglesfield fit up a narrow staircase?
It's usually manageable. This is a memory foam and spring mattress, 135cm wide and 25cm deep, so it flexes a little but won't roll up like an all-foam design. Measure any turning stairs or tight landings before ordering, and check the delivery arrangements of whichever retailer listed on this page you buy from.
Is a double Eaglesfield a good choice for a guest room?
It's a sensible fit. The UK double handles visiting couples and solo guests alike, and the firm feel with a memory foam surface suits a wide range of sleepers, useful when you can't predict who's staying. Its 135 x 190cm footprint also leaves space in a smaller spare room for a wardrobe and drawers.
