Silentnight Mirapocket Range Review
Where Silentnight becomes genuinely worth buying. The trick is knowing the number in the name does not describe the mattress you are buying unless you are buying a king.

Verdict
This is where Silentnight becomes genuinely worth buying. Individually pocketed springs rather than the linked coils of the Miracoil range, with the number in the name indicating spring count in a king size. The trick is knowing that the number does not describe the mattress you are buying unless you are buying a king.
Buy it if
You want an established UK manufacturer, pocket springs, and the ability to compare the same model across eight retailers.
Avoid it if
You want a long trial, or you are buying through a retailer that offers only unused-mattress returns.

The scores
Proper pocket springs from an established manufacturer, widely available and widely discounted.
The multi-retailer market means a determined buyer can do very well on price.
Genuine pocket springs. Support scales with the model number you choose.
A pocket spring unit moves air properly.
Better on the higher models. Varies across the range.
Individually pocketed springs. The key advantage over Miracoil.
Sixty nights direct only. Third party purchases usually get less.
The spring number does not mean what you think
Read this before comparing
A Mirapocket 1200 has around 1,200 springs in a king size. A double of the same model has fewer, and a single fewer still, because the spring density stays roughly constant while the area shrinks.
Retailers routinely quote the king figure against every size, which is how a single mattress ends up advertised with 1,200 springs when it contains closer to 800. This is not usually dishonesty, it is a listing copied from the range specification, and the effect on a buyer comparing models is the same either way.
How to actually shop the Mirapocket range
Silentnight sells through Argos, Dunelm, Amazon, Very, John Lewis and independents, each setting its own price and running its own sales. That is unusual in this category and it changes how you should buy.
With Emma or Otty there is one price and the only question is the discount. With a Mirapocket there are eight prices at any moment and the spread between them is often wider than any discount code.
The practical method: find the exact model name and spring count, then search that specific string rather than the brand. Searching Silentnight Mirapocket 1200 finds you the same mattress at five retailers. Searching Silentnight mattress finds you a sales page.
Then weigh the cheapest against buying direct, because only direct gets you the 60 night comfort exchange.
How many springs you actually need
Since the model number is a spring count, it is worth saying where the useful range sits.
Below about 800 in a king, you are into territory where the springs respond as groups rather than individually, and the mattress will feel closer to an open coil. Between roughly 1,000 and 2,000 is where most people should be. Above 2,000, the manufacturer is adding springs by using thinner gauge wire in smaller units, and the difference you can feel diminishes quickly.
A well made 1,200 with a decent comfort layer beats a poorly made 2,800 every time. Judge the comfort layer and the depth alongside the number, not instead of it.
A correction worth making
Commonly repeated, and wrong
Spring counts on Silentnight Mirapocket models are quoted by retailers against every size, and the figure in the model name refers to a king size. A single or double of the same model contains meaningfully fewer springs, because spring density stays roughly constant while the surface area shrinks. Anyone comparing a single Mirapocket 1200 against a king from another brand on spring count alone is comparing two different numbers.
Should you buy it?
Yes, and it is the part of the Silentnight range I would actually buy. Pocket springs from a manufacturer trading since 1946, at prices the multi-retailer market keeps honest.
Aim for somewhere between 1,000 and 2,000 springs in a king, buy direct if you are unsure about firmness so you keep the exchange, and avoid the Miracoil range entirely if you share the bed.
Questions people ask
Does a Mirapocket 1200 have 1200 springs?
In a king size, roughly. A double of the same model has fewer and a single fewer still, because spring density stays constant while the area shrinks. Retailers routinely quote the king figure against every size, so a single can be advertised with 1,200 springs while containing closer to 800.
How many springs does a mattress actually need?
Between roughly 1,000 and 2,000 in a king is where most people should be. Below about 800 the springs respond as groups rather than individually. Above 2,000, manufacturers add springs using thinner wire in smaller units and the difference you can feel diminishes quickly.
How do I get the best price on a Silentnight?
Find the exact model name and spring count, then search that specific string rather than the brand. The same Mirapocket appears at Argos, Dunelm, Amazon, Very and John Lewis at different prices, and the spread is often wider than any discount code.
