rubber tray

Most serving trays are about 15–15.5 inches long and roughly 11 inches wide (one lap-style tray listed at 15.5" x 11").

They use silicone grip nubs or dense non-slip dots on the top surface and rubber/TPR grip patterns on the bottom to help hold cups, plates, and bowls in place.

They’re suggested for indoor and outdoor serving such as TV dinners, breakfast in bed, lap meals, picnics, travel snacks, and can also double as a coffee-table or desk organizer.

Serving trays are listed as plastic and PP+TPR (one listing also mentions polyester). Ice and freezer molds are made of silicone.

Handles are described as easy-grip or ‘easy-grip handles,’ designed to provide a firm, secure grasp when carrying food and drinks.

Descriptions emphasize a space-saving, flat design for easy storage; some listings also note stackable, lightweight construction for convenient storage.

Ice is released by patting and pushing the soft bottom on stick-style trays; other silicone trays are reported as easy to pop out, with quick shape recovery for easy removal.
