The hotel bed, at home
Everyone remembers one hotel bed. The Tranquility 3000 was designed to be that bed, and then to solve the one thing those beds get wrong: they run warm.
Its identity is composure. A pillow-top crown gives the immediate, cushioned welcome; cooling gel memory foam beneath it contours to the shoulder and hip while drawing warmth away; and under both sits the collection’s highest spring count, 3,000 pocket springs in seven zones, held in an encapsulated edge. Indulgence on top, discipline underneath, and a cool head all night.
Three layers, one composed night
Open each layer to see what it does — and why plushness and support are not a trade-off here.
1 Pillow-top crown The first impression
A raised, pillowed sleeping surface built into the top of the mattress — the immediate sense of welcome you feel in a good hotel bed.
2 Cooling gel memory foam The comfort layer
Memory foam that contours to pressure points, with gel within it that draws warmth away — answering memory foam’s oldest complaint.
3 3,000 pocket springs in seven zones The support core
Three thousand springs, each in its own pocket, responding to you alone; seven zones hold the spine level from shoulder to hip.
Chosen to stay cool under a plush top
Every material inside the Tranquility was chosen for what it does through a full night, a full year, and a full decade.
A raised, quilted layer stitched onto the top of the mattress, so the first thing the body meets is cushion rather than structure. It is what gives a hotel bed its immediate welcome, and because it is built in rather than laid on, it stays where it was quilted.
Against a loose topper: no slipping, no bunching, and a surface that ages with the mattress rather than ahead of it.
Memory foam contours to the shoulder and hip, spreading your weight so pressure points release. The gel suspended within it conducts warmth away from the body, answering memory foam’s oldest complaint without giving up its contouring.
Against standard memory foam: the same pressure relief, markedly less stored heat.
Each spring sits in its own fabric pocket and answers only to the weight above it. Three thousand of them give the finest resolution of support in the collection, and seven zones hold the spine level from shoulder to hip while the surface stays plush.
Against open coils: support that follows your shape, and a partner’s movement that stays on their side.
The sleeping surface is woven from viscose, a smooth, cool-handed fibre that lets air and moisture vapour pass through the pillow top instead of holding them against you.
Against polyester covers: cooler to the touch and drier through the night.
A full wall of high-density foam wraps the spring unit, so the last inch supports like the centre: a larger usable surface, a solid place to sit, and a mattress that keeps its shape to the edge for years.
Against an unsupported border: no roll-off, no early sag at the sides.
Built in ordered layers, held to modern tolerances
Quilted onto the mattress rather than laid on it, flush to the edges, so the cushioned surface cannot shift, bunch or drift over the years.
Cooling gel memory foam seated once over the spring unit, in strict order — comfort that contours without trapping heat, and keeps its depth season after season.
The 3,000-spring core sits inside a full foam wall — edge-to-edge support, a solid place to sit, and a mattress that holds its shape to the last inch.
Who the Tranquility serves — and why
The pillow top and gel foam let the shoulder and hip settle deeply while the seven zones hold the waist — the collection’s most cushioned welcome for the side.
3,000 springs in seven zones keep the hips level and the spine straight; the crown fills the small of the back without letting it sink.
Gel within the memory foam conducts warmth away and the viscose surface breathes — the softness of a hotel bed without its heat.
The highest spring count in the collection resolves movement most finely: a restless partner becomes a rumour rather than an event.
Universally comfortable, immediately welcoming, and composed enough that no guest asks what is inside.
Where the Tranquility sits
A plush surface over a medium to medium-firm core: cushioned where you land, composed beneath.
Side sleepers get the deepest welcome: the pillow top and gel foam let the shoulder and hip settle while the seven zones carry the waist. Back sleepers get level hips under a surface that feels generous rather than firm.
If you love a plush bed but wake warm, this is the answer: the gel in the comfort layer conducts heat away and the viscose surface breathes, so the cushioning never becomes a duvet of its own.
If you want a taut, structured surface, choose the Arete. If you want natural fillings and a softer hand, choose the Natural. The Tranquility is for sleepers who want hotel-suite plushness with a cool head.
What a pillow top pocket sprung mattress is
The Tranquility 3000 is a pillow top pocket sprung mattress. Three things make it so. A core of 3,000 individually pocketed springs, arranged in seven support zones. A comfort layer of cooling gel memory foam seated over that core. And a pillow top: a raised, quilted layer of soft fillings stitched onto the surface of the mattress itself, so the first thing the body meets is cushion rather than structure.
Some mattresses offer a similar feel with a loose topper. This one builds it in. The pillow top is quilted flush to the edges and cannot slip, bunch or wander, and it ages with the mattress rather than ahead of it. Beneath the plushness sits the collection's finest spring resolution, which is why the surface feels generous and the support feels exact at the same time.
Plush where you land, composed beneath
The Tranquility sits at medium to medium-firm. That reads as a contradiction until you lie on it. The pillow top and gel foam give a deep, immediate welcome at the shoulder and hip; the sprung core beneath holds the waist and keeps the hips level. You sink into the surface, not through it.
Side sleepers get the most cushioned welcome in the collection. Back sleepers get a surface that fills the small of the back without letting it drop. If you want a taut, structured feel with no plushness at all, the Arete 1500 is the better choice; if you prefer a softer hand in natural materials, the Laurel Natural 2500. The Tranquility is for sleepers who want hotel-suite softness with structure underneath it.
Why 3,000 springs
Spring count describes resolution, not rank. Each pocketed spring answers only to the weight directly above it, so more, smaller springs read the body in finer detail: no plateaus, no pressure ridges, a surface that agrees with your shape everywhere. At 3,000 in a king size, the Tranquility carries the highest count in our Sleep Collection, above the 2,500 of the Laurel mattresses and the 1,500 of the Arete.
The practical difference is felt most by couples. Movement on one side is divided into thousands of small, local responses and stays there; a restless partner becomes a rumour rather than an event. Seven zones tune the springs down the length of the body, firmer under the hips and shoulders where the load is greatest, gentler at the head and feet. The full working guide to spring counts is in our pocket springs article.
Cooling gel memory foam, and why a pillow top needs it
Pillow-top mattresses have one traditional weakness: a thick, soft surface holds warmth. The Tranquility answers it with a layer of gel-infused memory foam directly beneath the pillow top. The foam contours to the shoulder and hip and spreads your weight so pressure releases; the gel suspended within it conducts warmth away from the body rather than storing it.
Above the foam, the sleeping surface is woven from viscose, a smooth, cool-handed fibre that lets air and moisture vapour pass through the pillow top instead of holding them against you. The result is the softness of a hotel bed without its heat, which is why we recommend the Tranquility to warm sleepers who had assumed plush was no longer for them.
33 centimetres, supported to the last inch
The Tranquility is 33 cm deep, among the deepest builds in the collection. The depth is the pillow top and the comfort layer; it is not padding for its own sake. Most fitted sheets with a deep or extra-deep pocket fit without strain, and a 33 cm mattress sits well on a divan or an upholstered bed frame alike.
Around the spring unit runs a full wall of high-density foam, so the last inch of the mattress supports like the centre. You can sleep to the edge without rolling toward the middle, sit on the side to dress, and expect the mattress to keep its shape at the border for years.
Small double to super king
The Tranquility 3000 is made in four UK sizes: Small Double 4ft (120 × 190 cm), Double 4ft6 (135 × 190 cm), King Size 5ft (150 × 200 cm) and Super King 6ft (180 × 200 cm). There is no single. Every bed we make is built to the same UK standard sizes, so the mattress and frame match; our bed size guide sets out the dimensions and what each needs from a room.
Prices run from £720 in small double and double to £1,200 in super king. Every size carries the same 60-night free home trial and 5-year warranty, and doorstep delivery is complimentary.
Tranquility, Comforto, Natural or Arete?
Four mattresses, four kinds of night. Choose the Tranquility for the pillow-top welcome over the collection's highest spring count, cool to sleep on, medium to medium-firm. Choose the Laurel Comforto 2500 if you want the deeper, slower embrace of a thicker memory foam layer and a firmer hand. Choose the Laurel Natural 2500 for natural wool fillings and the gentlest tension in the collection. Choose the Arete 1500 for taut, seven-zone support with gel cooling and no pillow top at all.
Still undecided? The Sleep Collection sets all four side by side, and our mattress buying guide works through tension, position and temperature in plain terms.
A short education in cool, cushioned sleep
The benefits of independent pocket springs
Support you can trust is support that is local: each pocketed spring carries only what is above it, so shoulders sink where they should and hips are held where they must be. The same independence is why a restless partner becomes a rumour rather than an event.
What a pillow top actually does
It lowers the pressure at the first point of contact. The shoulder and hip meet soft fillings before they meet foam or springs, so the body settles without having to be pushed into shape.
Why plush mattresses run warm, and how this one does not
Soft, deep surfaces trap air next to the body. Gel within the memory foam carries that warmth away, and a viscose surface lets moisture through, so the cushioning never becomes a duvet of its own.
Spring count is resolution, not firmness
Three thousand springs do not make a mattress hard. They make it precise: support that follows your shape in finer detail, and movement that stays where it started.
Zones, in one sentence
The body is not one weight, so seven zones tune the springs down its length: firmer where the hips and shoulders press, gentler at the head and feet, the spine held level.
What the first fortnight is for
A new pillow top is at its loftiest on night one and settles into its working shape over two or three weeks. The 60-night trial exists so that judgement is made on the mattress you will keep.
A mattress repays the care it is given

Everything you might still wonder
How does the 60-night home trial work?
Sleep on the mattress at home for up to 60 nights. If it is not right for you, contact the studio and we will arrange its return — we would rather you had the right mattress than the first one you tried.
Do I need to flip it?
No — the Tranquility is built in ordered layers and is not designed to be flipped. Rotate it head-to-toe regularly instead, monthly in its first year.
What is a pillow top pocket sprung mattress?
A pocket sprung mattress with an extra quilted layer of soft fillings stitched onto its surface. In the Tranquility 3000, that pillow top sits over cooling gel memory foam and 3,000 individually pocketed springs in seven zones.
Is the Tranquility 3000 firm or soft?
Medium to medium-firm. The pillow top and gel foam feel plush at the surface; the sprung core beneath is composed and supportive. Cushioned where you land, structured underneath.
Is a pillow top mattress good for side sleepers?
Yes, and this one especially. The pillow top and gel memory foam let the shoulder and hip settle deeply while the seven zones hold the waist, which is what side sleepers need to keep the spine level.
Will a pillow top mattress make me too hot?
Traditional pillow tops can. The Tranquility places gel-infused memory foam directly beneath the pillow top to draw warmth away, and its viscose surface lets moisture pass through. It is the mattress we recommend to warm sleepers who still want plushness.
Does a pillow top sag or flatten over time?
A loose topper can. The Tranquility's pillow top is quilted onto the mattress and flush to its edges, so it cannot shift or bunch, and it settles into its working shape in the first few weeks rather than collapsing. Rotate the mattress head-to-toe to keep wear even.
Are 3,000 pocket springs better than 2,000 or 2,500?
More springs mean finer resolution: support that follows your shape in more detail, and a partner's movement divided into smaller, more local responses. They do not make a mattress firmer. The Tranquility carries the highest count in our collection; whether it is the right one depends on the feel you want.
How deep is the Tranquility 3000, and will my sheets fit?
33 cm. Fitted sheets with a deep or extra-deep pocket, usually sold for mattresses up to 35 or 40 cm, fit comfortably.
Which sizes is it available in?
Small Double 4ft, Double 4ft6, King Size 5ft and Super King 6ft. There is no single size.
Does it reduce movement from a partner?
Markedly. Each of the 3,000 springs responds only to the weight above it, and the memory foam layer dampens what remains, so movement on one side largely stays there.
What is the difference between the Tranquility 3000 and the Laurel Comforto 2500?
Both are pocket sprung with a memory foam comfort layer. The Tranquility adds a built-in pillow top and gel cooling over 3,000 springs, for a plusher, cooler surface at medium to medium-firm. The Comforto has a thicker visco memory foam layer over 2,500 springs and a firmer hand, for a deeper, slower embrace.
Which of your beds does it suit?
Any of them. Every bed we make is built in the same UK standard sizes, with a slatted or sprung base that suits a pocket sprung mattress. The frames below are chosen to pair with it.
What does the 5-year warranty cover?
Manufacturing and structural faults in the springs, foams and cover for five years from delivery. Normal settlement of the pillow top in the first weeks is not a fault; a visible dip that remains when the mattress is unloaded would be. Full terms are on our warranty page.
