Layer Details
Stretch Knit Fabric
A soft, pliable cover that lets the fillings beneath contour to your body shape. You feel the comfort layers working rather than a stiff barrier between you and them.
Quilted Finish
The outer fabric is stitched directly to the surface fillings. This keeps everything in place, which means a flat, even sleeping surface without the fillings shifting about.
White Fibre Fillings
A lightweight, high-loft material that holds its shape over time. It's hypoallergenic too, a helpful point if you're prone to allergies.
High-density advanced foam comfort layers
A reflex foam layer designed to conform to your body by spreading your weight evenly. In practice that means reduced pressure points where you sink in most, typically hips and shoulders.
Open Coil Springs
Rows of hourglass-shaped springs joined at top and bottom by helical wires, forming one interconnected unit. This construction is hardwearing, though the connected springs mean you'll notice a partner's movement more than you would with pocket springs.

Key benefits
- Real room to spread out: At 30cm wider than the UK single, this size gives a solo sleeper genuine stretching space without demanding a bigger bedroom.
- Fits where a double won't: The UK small double is 15cm narrower than the UK double, which can be the difference between a door that clears the bed and one that doesn't.
- Boxed delivery suits tight spaces: The rooms this size fits, box rooms, lofts, studios, often have awkward access, and a vacuum-packed roll is far easier to manoeuvre than a rigid mattress.
- Medium feel across the full width: The reflex foam comfort layer spreads your weight evenly, which means fewer pressure points at hips and shoulders wherever you settle on the 120cm surface.
- Standard 4ft bedding is easy to find: The small double is a standard UK size, so frames and small double fitted sheets are widely available, with a standard double duvet on top.
This size suits you if...
You sleep alone and want more width than a UK single without giving up the floor space a full double would take, your bedroom, loft conversion or studio can't comfortably fit anything wider than 4ft, or you're furnishing a guest room that hosts couples a few weekends a year rather than every night.
Consider another size if...
Two of you share the bed every night, because the interconnected open coil springs transfer movement and 120cm is snug for nightly sharing. We'd recommend the UK double instead, which is 15cm wider.

FAQ's
What are the dimensions of the Highgrove Edmonton small double?
The UK small double measures 120 x 190cm, which is 4ft x 6ft 3in. That makes it 30cm wider than the UK single and 15cm narrower than the UK double, with the same 190cm length as both.
Is the Highgrove Edmonton small double big enough for a couple?
For occasional nights, yes, which is why it works well in a guest room. For nightly sharing it's a squeeze, and the Edmonton's open coil springs pass movement across the bed more than pocket springs would, so a restless partner is harder to ignore at this width. Couples sharing every night should size up.
Will the Edmonton small double fit in a box room?
Often, yes, and that's much of this size's appeal. We suggest a room of at least 2.4m x 2.8m so you can still open drawers and walk around the bed. The boxed delivery helps too, since a rolled mattress turns tight corners that a flat one can't.
Should I choose the Edmonton in a small double or a double?
It comes down to your room. The UK small double is 15cm narrower than the UK double, so if you sleep alone or your bedroom is compact, the small double leaves usable floor space. If you share nightly and the room allows it, the UK double is the better fit.
