About the Diamond Spring Free Deluxe Mattress
Last checked
A 29cm all-foam build sits behind the Diamond Spring Free Deluxe name, with no pocket springs despite the spring-led wording. The name is mildly misleading. The support comes from stacked foams: a graphite-infused visco-elastic Diamond Cool layer for contouring and heat movement, a medium-soft HRXComfort layer to stop the surface feeling boardy, and an HRXSupport base intended to hold the mattress flatter under load. For an all-foam mattress, 29cm is a generous depth; the conservative part is the support method, because the firm feel is created through foam density and layering rather than a pocket unit that can react more independently to shoulders, hips and weight differences. Compared with memory-foam hybrids, this should feel steadier and less bouncy, but also less lively at the edge and less responsive when changing position. The cover mix is functional rather than plush: 80% polyester, 19% polyethylene and 1% elastane, removable and washable at 40°C, with the polyethylene doing the cooling-cover work more than any natural fibre content. The graphite foam is a useful upgrade over plain visco foam, although “cooling technology” in an all-foam mattress still means heat management rather than the airflow of a sprung core.
Firm-mattress buyers who want a supportive foam feel are the clearest audience, especially back sleepers and some stomach sleepers who dislike the dipping sensation of softer memory foam. Owner sentiment is unusually one-sided here. Buyers repeatedly describe the mattress as very comfortable, supportive and helpful for back comfort, which fits the spec: a firm foam support base with a softer comfort layer above should give cushioning without the deeper sink of softer boxed foams. The supplied feedback does not show a repeated low-rating complaint pattern, so the sharper cautions come from the care sheet and construction. The slat rule is the practical one: gaps must be no wider than 7.5cm, because wider spacing can encourage excess dipping and affect the guarantee, which makes this a fussier match for older or widely spaced slatted frames than a more forgiving open-coil or pocket-sprung mattress. It also needs airing for 4 hours before use, and the manufacturer treats some settlement indentations as normal, so buyers expecting a permanently flat, showroom-tight surface may be disappointed over time. The firm foam build is less likely to suit lighter side sleepers who need shoulders to sink in easily, and couples with a large weight difference may prefer the independent response of pocket springs. A sensible shortlist mattress for firm-foam loyalists who value a washable cooling cover and back-supportive feel; pressure-sensitive side sleepers and couples prioritising edge strength or spring lift are better aimed at softer memory-foam hybrids or the mid-range pocket-sprung tier.
