Layer Details
Pillow top
A cloud-like pillow top with additional micro springs, which means a softer, cushioned surface sitting above the firm support below. It's sewn on rather than separate, so the comfort layer stays put.
Natural fibres layer
Generous layers of British wool, naturally cooling flax and farm-grown hemp. These fibres wick moisture and regulate temperature, which should help if you tend to sleep warm.
Pocket spring layers
7,440 responsive springs in total, combining high-density micro, Posturfil and Cortec pocket springs. Each spring moves independently, so you get support where your body needs it and less motion transfer across the bed.

Key benefits
- A small footprint that leaves room to live: At 90cm wide it leaves floor space for a desk or wardrobe, so a compact bedroom or loft conversion still functions as a room.
- Firm support for a growing sleeper: The firm feel and pocket spring support suit older children and teens well, giving a supportive base rather than a soft surface they sink into.
- Guest room quality without guest room compromise: In a spare room that doubles as an office, the UK single takes up little space while giving visitors a genuinely comfortable night.
- Natural fillings in a single size: British wool, flax and hemp regulate temperature, which matters in small rooms under a roof slope where heat tends to gather.
- Check the 30cm depth on raised frames: This is a deep mattress, so measure guard rail height before pairing it with a bunk, cabin or mid sleeper frame.
This size suits you if...
You sleep alone and want a firm, natural-filled mattress in the standard one-person size, you're buying a long-term bed for a teenager who's outgrown a children's mattress, or you're furnishing a spare room where the bed shares space with a desk and needs to stay out of the way.
Consider another size if...
You share the bed, or you're a single sleeper who sprawls and wakes against the edge. We'd recommend the Tennyson in a UK double instead, which is 45cm wider than the UK single and needs a room of at least 2.6m x 2.8m.

FAQ's
Will the Harrison Spinks Tennyson UK single fit a bunk bed?
The width fits: a UK single at 90 x 190cm is the standard bunk size. The depth is the problem. The Tennyson is 30cm deep, which will sit above the guard rail on many bunk, cabin and mid sleeper frames. Measure the rail height first, and check the frame maker's maximum mattress depth before buying.
What room size do I need for the Tennyson in a UK single?
We suggest allowing at least 2.1m x 2.8m of floor space. That gives you room to walk alongside the bed and open drawers or a wardrobe. In a child's room where the bed competes with toy storage and a desk, the UK single's 90cm width is the main reason to choose it.
Is the UK single Tennyson a good choice for a child?
For older children and teens, yes: firm pocket spring support and breathable natural fillings make a sensible long-term bed. It's a significant spend for a child's room, though, and lightweight sleepers may find the firm feel a little unforgiving on their side. For a young child, a simpler mattress they'll outgrow may make more sense.
Is the Tennyson UK single long enough for an adult?
At 190cm, or 6ft 3in, it suits most adults. If you're very tall, though, sizing up helps: the UK single is 10cm shorter than the UK king as well as 60cm narrower, so taller solo sleepers with the space get both extra length and stretching room by moving up.
Can two singles work instead of one bigger Tennyson?
In a guest room or a shared children's room, two UK singles are often more flexible than one large bed: they can be separated, pushed together or moved between rooms. Each needs its own walkway, so measure carefully. The prices shown on this page are updated as retailers change them, so compare per-mattress cost there.
