Layer Details
- Pillow top surface. A deeply filled pillow top with micro springs and natural fillings, which means a softer, cloud-like feel at the surface before you reach the firmer support below. This takes the edge off the firm rating for the first few centimetres.
- Natural fillings. Fully traceable British wool and cotton, plus hemp and flax sourced straight from the Harrison Spinks farm. Natural fibres like these help the mattress breathe, which means a cooler night if you tend to overheat.
- Pocket springs. 11,000 responsive springs in dynamic layers of high-density micro, Posturfil and Cortec™ pocket springs. Six layers adapt to your body as you sleep, relieving pressure while letting air move through the mattress.

- Real room to spread out alone: At 120cm wide you get 30cm more than a UK single, which means you can shift position through the night without meeting the edge.
- Fits rooms a double would crowd: It's 15cm narrower than a UK double, so a box room or loft bedroom keeps walking space beside the bed.
- Firm support at a compact width: The 11,000 springs across six layers give the same close-fitting firm support here as in the larger sizes, in a frame-friendly 4ft footprint.
- Natural fillings for a smaller space: Wool, cotton, hemp and flax breathe well, useful in compact rooms that can run warm with the door closed.
- Standard 4ft bedding is easy to find: The small double is a standard UK size, so sheets and frames are widely stocked, although the 35cm depth means you'll want deep fitted sheets.
This size suits you if...
You sleep alone, you've outgrown a UK single and you like a firm feel, but your room can't take a full double. Or you're kitting out a guest room or holiday let where couples stay occasionally rather than nightly, and you want a mattress built to last through years of intermittent use.
Consider another size if...
You share the bed every night, because 120cm is snug for two adults long term. We'd recommend the UK double instead, which is 15cm wider and needs a room of at least 2.6m x 2.8m.

Is a small double Fitzgerald big enough for a couple?
For occasional nights, yes. At 120cm wide two adults can share comfortably enough for a weekend stay, which is why this size works well in a guest room. For every night, that width feels tight, especially on a firm mattress where you don't sink towards the middle. Couples sharing nightly should look at the UK double or UK king.
What room size do I need for the Fitzgerald small double?
We suggest a room of at least 2.4m x 2.8m. That leaves enough space to walk round the bed and open drawers, which matters in the box rooms and loft conversions this size tends to end up in. The mattress itself is 120 x 190cm, so measure the sloping-ceiling side of a loft room carefully.
How does the small double compare to the UK double for this mattress?
The UK small double is 15cm narrower than the UK double and the two are the same length. That 15cm often decides whether bedside tables fit on both sides, or whether the door clears the bed frame in a studio flat. The construction, firmness and 35cm depth are identical across both sizes.
Is the Fitzgerald small double good for a teenager?
It suits a teenager who has outgrown a UK single but whose room can't spare the width of a full double, since it adds 30cm of width at the same 190cm length. The firm feel supports a growing back well, although a very light sleeper may find it unforgiving. It's a long-term purchase rather than a stopgap.
What bedding fits the Fitzgerald in a small double?
Small double (4ft) fitted sheets with a standard double duvet is the usual pairing, and 4ft is a standard UK size so both are easy to find. One caveat: this mattress is 35cm deep, so check the sheet's stated depth before you buy, as standard fitted sheets may not stretch over the pillow top.
