Layer Details
Cover
A wool-blend cover woven in-house, fire retardant without chemical treatments. That means natural flame resistance rather than sprayed-on chemistry.
Fillings
Responsibly sourced, fully traceable British wool, hemp and flax grown on the Harrison Spinks farm, alongside soft, breathable cotton. Natural fibres like these help regulate temperature, which matters if you tend to sleep warm.
Micro springs
A layer of 2,500 high-density micro springs, which means the surface can contour to your shoulders and hips even though the overall feel is firm. It's cushioning without softness, in effect.
Pocket springs
The award-winning Advanced Cortec pocket spring system uses a spring-within-a-spring design for dynamic support. In practice, the mattress responds differently to lighter and heavier pressure, adapting as you move.

Key benefits
- Real space for a solo sleeper: At 120cm wide, the UK small double is 30cm wider than the UK single, which means a firm surface you can actually spread across.
- A double feel in a smaller room: It's 15cm narrower than a UK double, so it fits box rooms, studio flats and loft conversions where a standard double would crowd the walls.
- Same firm build as the bigger sizes: You get the same Advanced Cortec spring-within-a-spring system and micro spring layer, so the smaller footprint doesn't mean a lesser mattress.
- Natural fillings for warm rooms: British wool, hemp, flax and cotton help regulate temperature, useful in the compact bedrooms and loft spaces where a 4ft mattress often ends up.
- Easy to dress: 4ft is a standard UK size, so small double fitted sheets are simple to find, and a standard double duvet works on top.
This size suits you if...
You sleep alone but have outgrown a single and want proper room to stretch, or your bedroom is too tight for a 135cm frame and 15cm of saved width matters, or you're setting up a guest room where couples stay occasionally rather than nightly. The firm feel suits you if you want solid support rather than a plush, sink-in surface.
Consider another size if...
You share the bed every night and want space to sleep apart comfortably. This model has no standard UK double, so we'd recommend the UK king instead, which is 30cm wider and 10cm longer; allow at least 2.7m x 2.9m for it.

FAQ's
Is a small double big enough for two people every night?
For occasional nights, yes, which is why the UK small double suits guest rooms well. For nightly sharing, 120cm is tight, especially on a firm mattress where neither of you sinks towards the middle. Since the Pure Splendour Firm skips the standard UK double, couples should look at the UK king, which is 30cm wider and 10cm longer.
Will the Pure Splendour Firm small double fit in a box room?
Usually, yes. The mattress measures 120 x 190cm and we suggest a room of at least 2.4m x 2.8m, which leaves space to open the door and walk down one side. In a loft conversion, the narrower width also helps you keep the bed under usable head height.
Why does Harrison Spinks make a small double but no standard double?
The Pure Splendour Firm comes in UK single, UK small double, UK king and UK super king only. If you were planning on a UK double, the choice becomes the UK small double at 15cm narrower, or the UK king at 15cm wider and 10cm longer. Room size usually decides it: the UK king needs at least 2.7m x 2.9m.
Is the small double a good size for a teenager?
Often, yes. It's a sensible step up once a single feels cramped: 30cm of extra width, the same 190cm length, and only a modest loss of floor space in a smaller bedroom. Bear in mind this is a genuinely firm mattress, so a lightweight teenager who sleeps on their side may find it a little unyielding.
How much floor space does a UK small double need?
The mattress itself is 120 x 190cm, and we suggest a room of at least 2.4m x 2.8m so you can get around the bed and open drawers. That's our guidance rather than the manufacturer's, and it's a minimum: measure your own room with wardrobes and door swing in mind before ordering.
