A. The sturdiest table with wide armrests: The clover-shaped home sofa table features longer table legs, rubber grips that generate friction, and wide hinges. It is more stable and compatible with most sofa armrests. B. Suitable for sofas of various sizes: The first impression of this foldable table is the heaviness of its hinges and spring clips. It can provide a clamping range of 12 inches wide for medium - wide armrests. C. Firm grip and no sliding: The rubber grips that generate friction work. They can prevent the tray table from sliding, allowing one to safely place a drink next to the remote control. D. Space - saving: This small table (with dimensions of 33×23 cm) takes up less space than an ordinary dining TV tray. When not in use, it can be folded into a compact form only 2 inches high and stored under the sofa. E. Free trial, zero risk: It's not easy to determine whether this foldable small table is suitable for one's sofa armrest. So one can try this sofa tray first. If it can't save space for chairs of any size or keep items within reach and stable, one can make a further judgment.
