For a permanent or temporary solution to your question of storage this Tesco trunk is ideal.
This large trunk in brown faux leather will blend well with its surroundings, no matter where you put it. May be in the study for storing documents. Or In the kids’ room for storing toys. Perhaps in the lounge for storing music or photo albums.
If required only temporarily, the Tesco trunk collapses almost flat for storing away until next time. Requires self-assembly.
