Background

About Ergoflex

Ergoflex sells one mattress online, the Ergoflex 5G, a rolled memory foam model delivered in a box. The brand’s FAQ page says it has been around since 2006 and explains why there is only one Ergoflex mattress. The trading company, Ergo Flex Limited, was incorporated on 27 March 2007 according to Companies House, with its registered office in Whitley Bay, Tyne and Wear.

The weight limit, trial, guarantee and certifications are from the same Ergoflex FAQ, which also states manufacture to the UK fire standards BS 5852 and BS 7177. Prices are Ergoflex’s regular prices in September 2026. The savings the Ergoflex homepage shows are measured against what it calls a Direct Competitor Price, defined in its footer as “the closest comparable premium mattress to the Ergoflex® 5G”, not against an earlier Ergoflex price, so they are not a sale in the usual sense.

Where it ranks with us

The Ergoflex 5G is first in our best foam mattresses comparison and second among our best memory foam mattresses. It also appears ninth in our king size mattress comparison, and features in our rankings of mattresses in a box and mattresses for side sleepers. Our Ergoflex 5G review covers the layers and prices size by size.

Who the 5G is for

Ergoflex suits someone who wants a proper memory foam feel and prefers one well-documented model to a range of near-identical ones. It suits heavier sleepers less well: the FAQ recommends the mattress for people up to 18 stone and asks anyone above that to contact the sales team first. The 30-day trial is also short against the 101 nights GhostBed and the 200 nights Dormeo give on their boxed mattresses, and Ergoflex asks you to sleep on the 5G for twenty-one nights before you decide.
