Start by measuring the clearance under your sofa where a C-shaped base slides. Leaving a bit of extra room can help the base glide smoothly.

• Height: Compare your sofa seat height with the table’s adjustable range so the surface lines up comfortably for eating, reading, or laptop work.
• Base depth: Make sure the foot reaches far enough under the couch for balance.
• Top size: Choose a narrow top for small spaces; go wider if you want room for a laptop and snacks.
• Flooring: On thick carpet, larger casters can roll more easily; fixed feet can suit hard floors.
• Specs: Check the listed dimensions and weight capacity on the product page.

Stability generally comes from a good fit under the sofa, even loading, and a level surface.

• Position: Slide the base fully under the couch and keep heavier items centered over the frame.
• Leveling: Adjust the feet (or wheels) so the table sits flat; periodically tighten hardware as needed.
• Casters: If your table has wheels, lock them before use.
• Surface: Avoid soft, sloped, or uneven flooring that can cause wobble.
• Load: Follow the product’s listed weight capacity and avoid leaning on the edge.
• Liquids: Use coasters and keep drinks away from power components on models with charging.

Routine care helps under-couch tray tables look good longer, but methods vary by material.

• Metal frames: Wipe with a damp cloth and mild soap; dry thoroughly to help prevent surface spots.
• Wood or bamboo tops: Use a soft, slightly damp cloth; avoid abrasive cleaners. Coasters can help reduce rings and heat marks.
• Tempered glass: Apply glass cleaner to a cloth (not directly to the surface) to minimize streaks.
• Charging areas: Unplug before cleaning around outlets or USB ports, and keep moisture away from power components.
• Hardware: Periodically check and retighten screws to reduce wiggle from everyday use.

Tables with integrated power add convenience, and a few habits can support safer use.

• Power source: Plug into a properly grounded wall outlet and follow the guidance in the product manual.
• Ratings: Check the listed amperage/wattage and avoid exceeding the combined load.
• Liquids: Keep drinks away from the outlet box; use designated cup holders if available.
• Cable routing: Run cords along the sofa base or wall to reduce trip hazards; simple clips can help manage slack.
• Unplug: Consider unplugging during extended periods of non-use.
• Inspection: If you notice wear or damage on cords or the outlet module, stop using it and contact the manufacturer for guidance.

Options can vary by item and seller, but there are a few places to check.

• Product page: Look for downloadable manuals, parts lists, or care guides in the listing details.
• Seller or manufacturer: Use the contact information in your order details or the manual to request hardware like screws, feet, or casters.
• Compatibility: If using universal hardware, match size, thread type, and material as closely as possible.
• Order support: For missing components on arrival, review the options shown in your Walmart account’s order details.
• Documentation: Keep the instruction booklet and any part numbers to make future requests easier.
