We contacted this organization regarding the manufacture of a two-level shelving. We were offered an interesting option that completely satisfied our need. The design turned out to be universal, everything is modular and collapsible "for all occasions".
I recommend it to anyone who wants to optimize storage space.
The work on the installation of the handrail was carried out efficiently and on time. We took into account all the wishes and possible nuances during installation. They always meet us halfway. Thanks :)
