What to know before buying

Listing details to confirm

Listing details are inconsistent about the spring configuration: details identify Bonnell Coil and 6 coils, while the title and feature copy describe innerspring and an enhanced 6-turn coil, and the item type name says pocket spring. Foam is also described as both comfort foam and gel foam. Confirm the selected listing's construction before purchase. The claimed hypoallergenic property and promotional health or motion-isolation benefits are not independently substantiated here.

Who is it for?

A good fit for

Adults seeking a double mattress with a specifically firm or extra-firm feel.
Bedroom or guest-room setups where the listed double dimensions fit the bed base.

Less suited to

Sleepers who prefer a plush or soft surface.
Buyers who need a confirmed spring type or verified health and motion-isolation performance without clarifying the inconsistent listing details.
