The BONTEC 4 step ladder (model TZ04) sits at number one in this guide. It is a folding steel step stool with a detachable tool tray, listed at £58.97 with 4.8 out of 5 from 1,764 ratings and a best sellers rank of 5 in Stepladders. The load figure is the one number that holds together: the title says 150kg and the first bullet says 150kg, and the two agree — which is more than several listings in this guide manage.

The fold thickness does not hold together as neatly. Bullet three says the ladder folds flat to 7cm, and bullet four repeats that 7cm in a folded size of 159cm x 46cm x 7cm. The product details below, under Item Dimensions, give 46 x 12.7 x 146.1 centimetres — a 12.7cm measurement that matches neither the 7cm fold nor the 46cm figure both sources share. The same bullet four also gives a folded length of 159cm while the open height in the same sentence is 146cm, so the folded version is listed as 13cm longer than the open one. Everything on this page is taken from the BONTEC listing on Amazon; we have not measured or tested the ladder ourselves.

## Questions people ask

**How much weight does the BONTEC 4 step ladder take?**

The title and the first bullet both give 150kg, and unlike some listings in this guide those two figures agree with each other.

**How thick is it when folded?**

Bullet three says it folds flat to 7cm, and bullet four repeats 7cm inside a folded size of 159cm x 46cm x 7cm. The product details give 46 x 12.7 x 146.1 centimetres under Item Dimensions, so one of the two thicknesses on the BONTEC page is not the folded one.

**Does it arrive assembled?**

Yes — the BONTEC listing says the folding step stool arrives pre-assembled and ready to use, and that the tool tray installs without tools.

**What are the open dimensions?**

The BONTEC TZ04 listing gives an open size of 146cm x 94cm x 46cm and a top platform of 36cm x 27cm.

**What is it made of?**

Thickened steel tubes with wide reinforced pedals, a sponge-covered handrail and rubber feet, according to the listing. It is listed as not extendable.

**Is it heavy to move around?**

The bullets give a net weight of 8.5kg and the product details give 8.48kg under Item Weight. BONTEC calls it lightweight and easy to move.
