Assessed from the specification published by Mattress Man, captured September 2026, and from regular price comparison across our UK retail partners.
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. At £699 to £900 depending on size, 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.

Who's it NOT for?
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.
Sleepeezee Tranquil 1200 Mattress
View all mattresses
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.
What sizes is the Sleepeezee Tranquil 1200 available in?
It comes in UK Single, Small Double, Double, King and Super King, priced from £699.00 up to £900 depending on the size you choose.
How quickly can the Sleepeezee Tranquil 1200 be delivered?
Mattressman offers free next day delivery on this mattress, with a handling time of 0 to 1 day and transit of 1 to 3 days. Delivery terms will differ if you buy from another retailer.
