Frequently Asked Questions
How heavy is it really?
About 100 lb — heavy enough to feel solid and stable, light enough that one person can move it without a plan.
How much assembly is needed?
The included hardware and instructions get it built in 20–40 minutes; the smaller pieces arrive ready or near-ready as shown. Two people make it quicker.
What weight can it take?
The rated capacity is in the specs — honest for the class, and the frame is built to it. Normal use stays well inside the margin.
Is it quiet enough for an apartment?
Designed for indoor use with the noise kept to the mechanism, not the floor — the anti-slip base is the difference. Neighbors hear less than you would fear.
How much space does it need?
The footprint and folded size are in the photos — the folding designs tuck against a wall or behind the couch between sessions. Measure your spot and it fits.
Does it need power or batteries?
The power setup is in the specs — rechargeable and battery models run anywhere, and the corded ones stay where the outlet is.
