Rank #8 in Best Small Double Mattress 2026: 10 Ranked, Coil Counts Compared
SZsuilong 4ft Small Double Mattress, 28cm
Price and rating as shown on Amazon when we collected them. Both change.
The SZsuilong 4ft small double mattress is the eighth entry in this guide: a 120x190cm hybrid that pairs pocketed springs with foam and comes in one firmness only, medium. It costs £106.24, weighs 19.2kg and holds 4.5 stars from 256 ratings.
Its finding here is a number that is missing rather than wrong. The rest of this guide argues over spring counts — listings that log 7 coils for a 7-zone unit, or 90 for a 9-zone one — but SZsuilong simply never publishes a coil count at all. It sells the same 7-zone pocket spring story as everyone else and leaves the figure out. The listing does get one thing right that others in this guide get wrong: the title says 11 inch and the spec sheet says 28cm, and 28cm really is 11 inch, so the two agree.
Everything below comes from the Amazon listing as it appears, not from any testing we carried out.

Questions people ask
How many springs does the SZsuilong 4ft small double mattress have?
The listing does not say. It describes 7-zone pocketed carbon steel springs but publishes no coil count, so there is no figure to check the zoning claim against.
How thick is it?
The spec sheet gives 28cm and the title says 11 inch. Those agree — 11 inches is roughly 28cm — but the same listing also calls 28cm the depth, so the wording is loose even where the number is consistent.
What are its actual dimensions?
The title and size field both say 120x190cm, the 4ft small double footprint. The field headed L x W x Thickness reads 28L x 120W x 190Th centimetres, which puts the 190 figure in the thickness slot.
What firmness is it?
Medium. SZsuilong lists the firmness as Medium and describes the mattress as medium firmness, the most popular choice, intended to relieve pressure and lower back pain.
Can one person carry it?
SZsuilong says it ships vacuum-compressed and rolled into a standard box and calls it easy for a single person to carry. The listing gives the weight as 19.2kg.
Is there a trial period?
The listing mentions a 100-night risk-free sleep. It does not give further terms, and reviews describe delivery plus a service that removed an old mattress.
