Rank #7 in Best Single Mattress 2025: 10 Ranked, and the Coil Counts That Do Not Add Up
SEZMOONSI 27cm Hybrid Single Mattress
Price and rating as shown on Amazon when we collected them. Both change.
The SEZMOONSI Hybrid Single Mattress is a 90 x 190 x 27 cm hybrid — memory foam over pocket springs — at £75.99. It is the cheapest entry in our guide to single mattresses and it sits at number seven, carrying a 4.5-star average from 152 ratings. The advert leans hard on an orthopaedic, 7-zone independent pocket spring story.
The catch sits four rows further down in SEZMOONSI's own specification table. The row headed 'Number of Mattress Coils' reads 21, and 21 coils is not a figure that describes a 7-zone spring unit in a 90 cm wide mattress. The row headed 'Number of Layers' reads 1, on a mattress the bullet points describe as memory foam built over an innerspring core. Everything on this page comes from the Amazon listing as it stands, not from a mattress we have slept on or measured.
