The Sleepeezee Tranquil 1200 uses 1,200 traditional pocket springs, which means each spring moves independently, so you feel supported where you need it and less of your partner's movement. It also has edge-to-edge encapsulated support, which means the springs run right to the sides, so you can sleep near the edge without that rolling-off feeling. Detailed information on the comfort layers is thin on the ground, so if you want to know exactly what sits above the springs, it's worth asking the retailer before you buy.

Why should you choose this mattress?
A medium firm feel suits most sleepers, although lightweight side sleepers may find it a little too firm for their shoulders and hips. The 1,200 pocket springs respond to your body individually, which means better pressure relief and less motion transfer than a traditional open coil mattress. Edge-to-edge encapsulated support is a genuinely useful touch: it firms up the perimeter, so couples sharing a smaller bed can use the full width of the mattress. It sits at a sensible mid-range price for a pocket sprung mattress from an established British brand. If you buy through Mattressman, they list a 60-night trial and free next day delivery.
Key features & layer details
We’re still collecting information on this mattress. Unfortunately, we don’t have its key features yet.
Best suited for?
Couples
Pocket springs that move independently mean less of your partner's movement reaches you, so shared nights should feel more settled and undisturbed.
Back sleepers
A medium firm feel gives a fairly solid, level surface, which suits those who lie on their backs and want steady support from the springs.
Combination sleepers
Each of the 1,200 pocket springs responds on its own, so the support adapts as you shift between positions during the night.
If you like a soft, sink-in feel, this medium firm tension will probably feel too solid. Buyers who want full transparency on materials may be frustrated too, as the listing gives little detail about the comfort layers. And if a long, clearly stated guarantee matters to you, none is stated on the retailer page.
Save on an earlier or ex-display model
Some retailers still sell the earlier version of this mattress, or ex-display and returned stock at a lower price. These are the sizes where it costs less than the current model's best price.

FAQ's
How firm is the Sleepeezee Tranquil 1200 mattress?
It's rated medium firm, which suits back and combination sleepers who want a supportive surface with a little give. Lightweight side sleepers may find it slightly too firm around the shoulders and hips.
How many springs does the Sleepeezee Tranquil 1200 have?
It contains 1,200 traditional pocket springs. Each spring is sewn into its own fabric pocket and moves independently, which means the mattress contours to your body and you feel less movement from a partner. It also has edge-to-edge encapsulated support, so the springs extend right to the sides.
Does the Sleepeezee Tranquil 1200 come with a sleep trial?
Mattressman lists a 60-night sleep trial on this mattress. That's the retailer's own offer rather than a manufacturer promise, so if you buy elsewhere, check that retailer's returns policy before ordering.

It comes in UK Single, Small Double, Double, King and Super King.
How quickly can the Sleepeezee Tranquil 1200 be delivered?
