💬 Frequently Asked Questions (Q&A)

Q: Will installation be troublesome? Do I need professional help?
A: Not at all. This shelf is designed for DIY assembly using snap-in principles, making assembly as simple as building blocks. Instructions included, you can complete basic assembly within 15 minutes.

Q: What’s the difference between main frame and add-on frame? How should I buy?
A: Each independent unit (or the beginning of each row) must be a main frame. If you need continuous placement, the rest can be add-on frames. For example, to create a 3-meter long bookshelf, you only need 1 main frame + 2 add-on frames.

Q: Will the metal material have odors? Is it safe for children’s rooms?
A: Rest assured. We use physical spraying process rather than paint, with no formaldehyde or volatile odors. Rounded corner treatment and anti-tip design make it very suitable for homes and children’s rooms.

Q: If I fill it with heavy hardcover books, will the shelves sag?
A: Our cold-rolled steel is thickened and structurally designed with reinforcement ribs. Within the rated load (120kg-170kg), shelves won’t show visible deformation even with long-term use.
