The little screws keep coming loose from underneath... I would prefer the seat base to be made of another material instead of plastic so that the screws can be screwed in more securely

Wasted money!
From the very first assembly, the screws come off one by one since the plastic seat they screw into melts like paper. The result is that in the end, you worry more about whether your person will step on the screw that has come off and is particularly sharp. The description that mentions 110 kg is immediately contradicted by the leaflet inside, which states 100 kg. As soon as you take it out of the ridiculous packaging, you start doubting even the 70...

For its price, it is excellent (I got it for about 20 euros)! You will need a Phillips screwdriver and pliers or a wrench to assemble it. Simple construction, looks sturdy…

The plastic is not suitable for heavy weight, the material is not good at all and the screws underneath keep coming loose, they constantly need tightening.

I had bought it for my mom as she walked with the P and went alone for a bath; it was and is excellent

Small size so it can fit in older bathtubs and sturdy construction. The only downside is that because it has a safety nut for the central screw, it requires an Allen key or pliers to tighten.

Excellent product. Lightweight, sturdy, and easily adjustable to the bathtub. It did the job perfectly for which it was purchased.

As a bath seat, it is stable, in a bathtub with a width of about 32 cm, which is curved. HOWEVER, it comes without assembly instructions as mentioned in the other reviews. The central screw with the thread and the nut was not clear at all how it could be securely screwed, given that it holds the two sets of legs together. As a result, two people were involved in the assembly, one to hold the screw steady and the other to screw the nut with pliers - one of whom was the one with the broken leg, for which we also bought the stool. In the end, we assembled it and it seems stable, but definitely for something you buy in order to be safe, usage instructions would help.

It also works in a bathtub, which has a slight curve at the bottom. Therefore, it is convenient for bathtubs

His legs are so well aligned that they step on all four on the floor.
Be careful not to tighten the screws too tightly, as we are dealing with soft metal (aluminum) and plastic.
I am attaching two photos for the correct assembly. First, we screw in the central screw with the dense thread, just enough to allow the two P's that form the two aluminum parts to move evenly. A washer does not go into the central screw because it does not fit there. The lock nut is for safety so it does not unscrew easily on its own. The package includes six special washers in case we lose two. Then we place the plastic part and gradually screw in the screws until the plastic sits well on the aluminum legs. Finally, we tighten a little more, including the central screw.
There are no suction cups on the soles, but soft plastic.

It seems to have good and well-made construction (the legs). Made of high-quality aluminum. However, I was not satisfied with the contact of the seat with the aluminum, which is very small. It should have been larger. It comes unassembled and without assembly instructions. It includes a screw with threading that presumably goes in the center, four sheet metal screws for connecting the aluminum part with the plastic, and 6 curved wheels that it is not clear exactly where they go.

I bought it for my grandfather and he is really very satisfied. My grandmother started using it too and considers it the best purchase they made. The bathtub is about 31.5 and this specific chair fits perfectly!

Functional, it has suction cups so it doesn't slip. Beautiful, it doesn't take up much space, I have it in a semi-circular shower. I consider it very useful for people with stability issues.
