If you prefer a firmer surface, perhaps because you sleep on your back or front, or you simply find softer mattresses leave you feeling unsupported, this is the sort of feel the Athens 1400 is built around. The pocket spring construction gives it an edge over open coil designs, which means support that responds to your body shape rather than the whole surface moving as one. At a from-price of £278 it sits at an accessible point for a branded pocket spring mattress. A firm ortho feel will not suit everyone, but for those who want it, the price and the retailer-listed 5 year guarantee make a reasonable case.

Who's it NOT for?
A firm mattress like this is unlikely to suit lightweight side sleepers, who may find it puts too much pressure on the shoulder and hip rather than letting them settle in. If you like a plush, cushioned feel, look at medium or softer options instead.

How firm is the Silentnight Athens 1400 Mirapocket Ortho mattress?
It is listed as firm. That suits back and front sleepers, and heavier bodies that need extra support, more than lighter side sleepers who often prefer a bit of give at the shoulder and hip.
What sizes does the Silentnight Athens 1400 come in?
It is available in UK Single, UK Small Double, UK Double and UK Super King, with prices ranging from £278 to £514 depending on the size you choose. A UK King size is not listed.
Does the Silentnight Athens 1400 have a guarantee?
Mattress Online, the retailer listing this mattress, shows a 5 year guarantee. Check the terms at the point of purchase, as guarantee conditions can vary by retailer.
Is the Silentnight Athens 1400 a pocket spring mattress?
Yes. It uses pocket springs, which sit in individual fabric pockets and move independently, so pressure on one part of the mattress does not drag the rest of the surface down with it. That tends to mean less partner disturbance than open coil designs.
