Bed cup holder questions: fit, placement and care

Steadi helps support one compatible drink on a reasonably level, supported spot on bedding. Smooth the covers and support the full base. Bedding and mattress movement still affect stability; Steadi is not spillproof.

No. Steadi does not seal an open drink or form a waterproof barrier over the mattress. A separate stable surface may suit you better when avoiding drinks on bedding is your priority.

Steadi fits container bases 2–3.15 inches across, inclusive. Measure the bottom, not the rim, and check handle clearance. The exact 40 oz Stanley Quencher H2.0 is confirmed; other models need their own check. Read the shared fit guide.

No. Steadi is freestanding. It does not clamp to a rail, tuck beneath a mattress or attach to furniture.

Either side can be considered if there is a reasonably level spot with full support for the base and enough room to reach the drink without knocking it.

Yes, with compatible drinkware and enough clear space for the full base. A hard surface does not remove the possibility of spills, especially near an edge or where the drink can be knocked.

Mattress movement can move or tilt the holder. Steadi helps resist tipping, but it cannot guarantee that the drink will remain upright when the bedding shifts.

Hand wash only. Rinse or wipe it clean and let it dry. Do not put it in the dishwasher.

Steadi is made by Steadi Labs in Orange, California. Purchases from this site use Steadi Labs checkout. See the current shipping information and return policy.

No. Steadi does not attach to a bed rail or prevent a drink from falling off an elevated bed. If you need an attached shelf or holder, choose one designed for your bed and follow its mounting and load requirements.

Wipe moisture from the container and holder and check that both are seated properly. Do not assume that a wet surface has the same grip as a dry one. Steadi is not a waterproof barrier for bedding. Compare coasters, cup holders and trays to separate surface protection from drink support.

Do not rely on it as a spill tray or a waterproof mattress protector. Liquid can reach the bedding. Follow the bedding or mattress manufacturer’s care instructions if a spill occurs.

Yes. Use one holder per compatible drink and leave enough supported space for each base.

The same 2–3.15-inch base range and handle-clearance checks apply. A cup’s age label, capacity or character design does not establish compatibility.

Check the recipient’s usual drinkware and where they would place it. It is most useful when both the container fit and the available supported space suit the product.

Steadi supports one compatible drink on its own base. A caddy or shelf may hold several items and may attach to the bed. Check each product’s mounting, support and load requirements. See Steadi’s options and the bedside comparison on the homepage.

We do not publish a tested grip-lifespan claim here. Inspect the holder for damage and confirm that your drink seats properly. If its fit changes or you have a concern, contact Steadi Labs.

Remove the drink before changing the bed’s position, then reassess the support. Steadi does not attach to the bed or secure a drink while the bed moves. Plan your bedside setup.

Use our shared first-use guide for fitting an empty container, choosing support and checking changed fit. It also explains sliding versus tipping and when to contact Steadi Labs. The guide is on our Couch site and covers the same Steadi product.

Steadi is 2.8 inches tall with a 5.2-inch footprint and weighs about 3.6 ounces. It is made from thermoplastic polyurethane (TPU) with Shore 85A hardness and is BPA free. See dimensions and fit guidance.

A hot drink in its own compatible cup is normal use. Check the cup’s base and handle clearance, and use a reasonably level, supported spot. Steadi does not seal the drink or prevent every spill. Hand wash the holder only; do not put it in the dishwasher or microwave.

The exact 40 oz Stanley Quencher H2.0 is confirmed to fit. Other models need their own base and handle check. Our model-specific fit guide explains the manufacturer dimensions available for the Owala 24 oz Tumbler and YETI Rambler Travel Mugs, and distinguishes them from confirmed Steadi fits. A brand name or capacity alone does not establish compatibility.
