An e-shop for beds, mattresses and bedroom furniture from the manufacturer’s own workshops, built on the sellio platform.
2026
Our task
Postele-spalne.sk is the e-shop of the Slovak manufacturer Wood Service – beds, mattresses, bed bases and bedroom furniture from its own workshops. We built the whole e-shop on the new generation of our Sellio system: the frontend runs on Nuxt 4 with server-side rendering, while product data and content come from an API-Platform backend.
We built the e-shop with agentic development – most of the code was written by AI agents under our lead. That is how we met a punishing deadline tied to the launch of the client’s TV campaign. The design workshops therefore ran directly in the code: we tuned changes with the client live on a working site rather than on static mock-ups.
Material configurations were the core of the project. Every bed can be ordered in dozens of decors and upholstery fabrics split into price tiers, and that choice carries through the whole purchase – product photos in the listing are recoloured according to the selected filter, a material sample can be ordered free of charge, and the chosen combination keeps its size and colour all the way to the cart.
Accessories are added to beds automatically by size – mattresses, bed bases, drawers or pillows in the colour of the upholstery. The cart and the “Added to cart” popup show photos of the selected combination, so the customer sees exactly what they are buying.
On top of the catalogue sits a content layer that sells: API reviews with filtering and pagination, video reviews, Heureka ratings, a “We were on TV” section, the shop’s own video series, a blog with categories, a store list with a map and a link through to the store detail, hotel furniture references and a form for a free 3D bedroom design.
