What to know before buying

Listing details to confirm

The listing is inconsistent about thickness: the title, size and dimensions give 22 cm, while a separate thickness field says 0.22 Centimetres. Confirm the intended depth before ordering. The listing also describes a mattress in a box but its explicit contents field says only “Spring”, so the package contents are not fully clear. The bed frame is not included, and the mattress needs 48–72 hours to expand before use.

Aggregate ratings are mostly in the four- and five-star categories, with a smaller three-star share. This gives a generally favourable but not uniformly positive snapshot, not evidence about specific performance: buyers should weigh it against their own needs for a 22 cm hybrid, noting the listing's conflicting thickness details.
