Key benefits
- Real stretching room for one: The UK small double is 30cm wider than the UK single, which means a solo sleeper can roll over or starfish without a limb hanging off the edge.
- Fits where a UK double will not: At 15cm narrower than the UK double, it can be the difference between a bedroom door that clears and one that scrapes.
- Pocket springs suit occasional sharing: Individual springs respond to each sleeper separately, which helps when guests share it for a weekend, as one person turning disturbs the other less.
- Standard 4ft size, easy to dress: Small double frames and fitted sheets are widely stocked in the UK, so you are choosing a common size rather than a compromise.
- Modest room requirement: We suggest allowing at least 2.4m x 2.8m, which brings box rooms, loft conversions and small second bedrooms into play.
This size suits you if...
You sleep alone and have felt cramped in a single, perhaps a teenager who has grown but whose room cannot lose any more floor space. Or you're furnishing a guest room or holiday let where couples stay occasionally but nobody sleeps nightly. It also suits downsizers whose new bedroom will take a bed 4ft wide but nothing more.
Consider another size if...
You share the bed every night and want proper personal space. The UK small double is manageable for two on occasion, but for nightly sharing we'd recommend the UK double instead, allowing a room of at least 2.6m x 2.8m.

FAQ's
What room size do you need for the Grand Duke small double?
We suggest allowing at least 2.4m x 2.8m. That is our own guidance rather than the manufacturer's, and it leaves enough space to walk around the bed and open drawers. If your room is tighter than that, measure carefully before ordering, as the mattress itself is 120 x 190cm.
Is the Grand Duke small double ok for a couple every night?
For occasional stays, yes, and the pocket springs help because each sleeper is supported independently rather than rolling into a shared dip. For every night, most couples find 4ft a squeeze. The UK double is 15cm wider at the same length, and we'd point nightly sharers that way.
Will the Grand Duke small double fit in a box room or studio?
Often, yes, and that is largely the point of this size. It is 15cm narrower than the UK double, which in a box room can decide whether the door still opens fully or whether you can stand beside the bed in a loft conversion. Check your room against our suggested minimum of 2.4m x 2.8m.
Should I choose the Grand Duke in a small double or a single?
If the room can take it, the UK small double. It is 30cm wider than the UK single and exactly the same length, so you gain sprawling room without needing a longer bed. For a teenager who has outgrown a single, that extra width usually matters more than anything else on the spec sheet.
Where can I buy the Grand Duke mattress in a small double?
Compare the retailers listed on this page. The prices shown here are updated as retailers change them, so what you see is current rather than a snapshot. It is a standard UK 4ft size, so finding a matching frame and small double fitted sheets is straightforward.
