Layer Details
- Cover. A knitted fabric cover with a smooth quilted surface. It gives the sleeping surface a soft, finished feel before you reach the firmer layers below.
- Filling. A layer of Geltex, a gel-infused foam that offers pressure-relieving comfort and breathability. In practice this means gentle cushioning at the surface and better airflow than traditional foam, helpful if you tend to sleep warm.
- Springs. The king size contains 1,000 individually pocketed springs delivering firm support and reducing movement transfer. Each spring responds separately, so the mattress contours to your shape and limits partner disturbance.

- The classic couples' footprint: At 135 x 190cm the UK double fits comfortably in most UK bedrooms, so you can keep bedside tables on both sides of the bed.
- Less partner disturbance in a shared size: Individually pocketed springs move on their own, which means at 67.5cm each for two people sharing, one person turning is less likely to wake the other.
- Firm support with a softened surface: A Geltex layer over the springs eases shoulders and hips slightly, so the firm feel doesn't arrive as a hard slab.
- Runs a little cooler for two: Two bodies generate more heat than one, and Geltex is designed for breathability, which helps a shared double stay comfortable overnight.
- Easy to dress: Standard double sheets and a 200 x 200cm double duvet are stocked everywhere, useful if you're furnishing a whole home and the budget is stretched thin.
This size suits you if...
You share the bed every night and your room suits the traditional couples' size rather than a UK king, or you sleep alone and want space to spread out, perhaps with a dog or cat claiming a corner. It also makes a solid guest room bed for visiting couples, since the firm feel suits back and front sleepers without dividing opinion too sharply.
Consider another size if...
You and your partner both like space and your room measures at least 2.7m x 2.9m. In that case we'd recommend the UK king instead: it's 15cm wider and 10cm longer than the UK double.

Is the Sealy Sterling UK double big enough for a couple?
Yes, for most couples. The UK double gives 67.5cm each for two people sharing, and because the pocketed springs respond independently, movement on one side transfers less to the other. If either of you is broad-shouldered or a restless sleeper, the UK king adds 15cm of width and 10cm of length, provided your room allows it.
What size room do I need for the Sealy Sterling double?
We suggest a room of at least 2.6m x 2.8m for a UK double, with around 3m x 3m the comfortable norm. That allowance leaves walking space around the bed and, in most rooms, enough wall for a wardrobe and bedside tables on both sides. This is our guidance rather than Sealy's.
How many springs does the Sealy Sterling have in a double?
Sealy publishes a spring count of 1,000 individually pocketed springs for the king size, but doesn't state a figure for the UK double. Smaller sizes of a mattress typically carry fewer springs across the narrower surface, so check with Furniture Village if the exact number matters to you. The firm feel and construction are the same across sizes.
Should I get the Sealy Sterling in a double or a king?
It usually comes down to your room. The UK double is 15cm narrower and 10cm shorter than the UK king, and we suggest at least 2.7m x 2.9m for the UK king against 2.6m x 2.8m for the UK double. If the bigger size would leave you squeezing past the bed each morning, stay with the double.
Where can I buy the Sealy Sterling double?
The Sealy Sterling is a Furniture Village online exclusive, which means you can't try it in a showroom first. Compare the prices shown on this page, as they're updated whenever retailers change them. Bear in mind it's a firm mattress, so lightweight side sleepers may find it presses on the shoulder and hip.
