## Before you buy

- The listing is inconsistent about thickness: the title says 11 inches, while the size and dimensions specify 28 cm. Its stated 135 × 190 × 28 cm dimensions and 27 kg weight should be treated as listing details, not independently confirmed measurements. The listing also gives 24–48 hours for full expansion, up to 72 hours in colder conditions, and recommends waiting 48–72 hours before sleeping on it. It claims a 100-night trial and 10-year warranty, but terms are not supplied.

## In the box

- 1 Manual (Included)
- 1 Mattress (Included)

## A good fit for

- Shoppers seeking a medium-firm double hybrid with both gel memory foam and pocket springs.
- Couples who value the listing’s motion-isolation claim and want to consider an independently sprung design.
- Buyers whose bed base is a box spring, slatted base or solid foundation.

## Less suited to

- Anyone who needs confirmed thickness before choosing bedding or matching a specific bed frame, unless the seller clarifies the 11-inch versus 28 cm listing.

## Customer feedback

Customer feedback highlights comfort and supportive feel, including reported interest in back-pain relief. That aligns with the listing’s medium-firm foam-and-pocket-spring design, but neither the product claims nor the feedback establishes a particular medical outcome. The overall ratings are strongly positive, though a small rating sample cannot show how the mattress will suit an individual sleeper.
- Positive themes: Customers describe the mattress as comfortable.
- Positive themes: Customers mention supportive qualities and back-pain relief.
