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
- Real room for two: At 75cm each for two people sharing, you can both change position without negotiating, which suits couples who have outgrown a smaller bed.
- Less partner disturbance: The pocket springs move independently, and across a 150cm width their motion isolation has more space to work, so one person getting up early travels less across the bed.
- Length for taller sleepers: At 200cm, the UK king is 10cm longer than the UK double, which anyone approaching six foot will feel at their feet every night.
- Firm support across the full width: The Cortec and Posturfil spring layers support edge to edge, so the outer 75cm feels as usable as the middle rather than a place you avoid.
- Natural fillings at scale: British wool, flax and hemp regulate temperature over the whole 150cm surface, helpful when two bodies share the bed and one runs warm.
This size suits you if...
You share the bed every night and want more personal space than a UK double offers, especially if you and your partner keep different hours and one of you leaves early. It also fits if either of you is approaching six foot, since the 200cm length gives your feet somewhere to go, or if a dog has become a permanent fixture and keeps claiming more than its share.
Consider another size if...
Your bedroom falls short of the 2.7m x 2.9m we suggest for a UK king, or you sleep alone. In either case we'd recommend the UK double instead, which needs at least 2.6m x 2.8m.

FAQ's
Is a UK king Tennyson big enough for a couple?
Yes, comfortably for most. Two people sharing get 75cm of width each, and because the Tennyson is firm with 7,440 independent pocket springs, you each get consistent support in your own half. If you both like to sprawl, or a dog joins you most nights, the UK super king adds another 30cm of width.
Will the king size Tennyson suit a tall sleeper?
At 200cm long, the UK king is 10cm longer than the UK double, and that extra length is often the real reason taller sleepers upgrade. Anyone approaching six foot gets room to stretch fully without their feet hanging off the end, and the firm support runs the whole length of the mattress.
What room size does the Tennyson in a UK king need?
We suggest at least 2.7m x 2.9m, which leaves room to walk round the bed and open drawers. New build master bedrooms can be tighter than they look once wardrobes go in, so measure with furniture in place. If your room is smaller, the UK double needs at least 2.6m x 2.8m and loses only 15cm of width.
Does the Tennyson reduce partner disturbance in a king size?
This is where the size and the construction help each other. Each of the 7,440 pocket springs compresses independently, so movement stays local rather than rippling across the bed, and the 150cm width puts more distance between you. If one of you gets up hours before the other, the sleeper left behind should feel very little of it.
Should we choose the UK king or UK super king Tennyson?
The UK king is 30cm narrower than the UK super king, and both are the same 200cm length. The UK king suits most couples and fits a room of at least 2.7m x 2.9m, while the UK super king needs at least 3m x 2.9m. Compare the retailers listed on each page, as prices are updated as they change.
