Ask for the assembly instructions, the tools required, the approximate working space and whether the maker recommends more than one person. Check if any wall or ceiling attachment forms part of the installation.
A product described as easy to assemble can still involve heavy sections, awkward access or a fixing task that needs professional help in your home. Look at the largest component and consider doorways, stairs and the position where you plan to build it. Confirm whether parts are supplied preassembled and whether cushions or accessories are attached during a particular stage. Avoid assuming you can fully assemble the furniture elsewhere and move it into place afterwards. Understanding the sequence before ordering helps you plan realistically and prevents appearance from overshadowing a practical task you may not be equipped to complete safely.
Distinguish tools included in the box from tools required for the entire installation. A supplied hex key may assemble the furniture while separate equipment and expertise are still needed for its specified wall attachment.
