Silentnight Ashford 1400 Pocket Comfort Luxury Ortho Mattress im Test

The Silentnight Ashford 1400 Pocket Comfort Luxury Ortho is a firm, 24cm pocket sprung mattress from Silentnight’s Premium Pocket collection, made in the UK and sold through Argos. Argos buyers rate it 4.7 out of 5 across more than 1,000 reviews and score its firmness 4.3 out of 5, as read on 5 October 2026.

How it is built

Inside are 1,400 Mirapocket springs, each in its own fabric pocket, zoned to give more resistance under the heavier middle of the body. The National Bed Federation’s Bed Advice UK guide explains that spring units can be “zoned” across the middle “to give extra support for heavier hips and shoulders”, which is the job zoning does here.

Above the springs sit layers of Eco Comfort fibre made from recycled bottles. Tufting, the stitched buttons you can see on the surface, holds those layers tight, so the mattress feels firmer and the fillings shift less over time. The cover is a quilted damask, and Silentnight designed it to match its Premium divan sets, according to the Argos product page.

Sizes and prices at Argos

Prices were regular, with no sale running. The small double costs more than the double. The mattress arrives flat, and the single alone weighs 23kg in its packaging.

Who it suits

The firm feel keeps the hips level for back and stomach sleepers and gives heavier sleepers a surface that does not dip in the middle. Side sleepers, especially lighter ones, are likely to find the shoulders and hips under pressure and should choose a medium model instead.

Silentnight backs it with a 5-year manufacturer’s guarantee. If the firmness turns out wrong, Argos’s 100-night comfort promise allows one exchange for another mattress of the same size.
