Tray table covers

What tray table covers are

Most economy seats have a tray that folds down from the seat back in front of you. First, business, bulkhead and exit-row seats usually have one that folds out of the armrest instead.

• A personal barrier: Your own fabric sits between the tray and your food, hands and laptop.
• Top and underside: Full sleeves wrap the whole tray, including the underside that knees and small hands touch.
• Often an organizer: Many add pockets for a phone, tablet, earbuds or water bottle, in place of the seat-back pocket.
• Reusable or single-use: Fabric covers go through the wash; Seat Sitters packs two adhesive-backed covers per kit, one for each flight of a round trip.
• Who makes them: Small specialist brands: Airplane Pockets, Go-Be Sleeves, Lusso Gear, Serenity Organizers and Seat Sitters.

How they work

Most covers rely on stretch. Elastic fabric pulls taut around the tray, so the surface stays flat while you eat or type.

• Stretch fabric: Polyester and spandex stretch to fit trays of different sizes; Airplane Pockets uses both.
• Sized for coach: Makers size their covers for standard coach trays, the fold-down kind in most economy seats.
• Pockets that hang: On organizer covers, the pockets hang against the seat back when the tray is up and locked.
• Prop-up trays: A 2024 Forum Brands patent pairs a spandex sleeve with a water-resistant tray fixed by hook and loop.
• Adhesive backs: Single-use covers can stick in place; Seat Sitters’ tray covers have adhesive on the back.
• Packs small: A Go-Be sleeve weighs 1 ounce and rolls into a 3-ounce case that clips to a carry-on.

Types

• Plain sleeves: A single layer that wraps the whole tray, top and underside, with no pockets; Go-Be Solos are one.
• Organizer covers: A sleeve plus pockets for devices, snacks and a bottle, such as Airplane Pockets or Lusso Gear’s zippered cover.
• Cover, then tote: Serenity Organizers’ cover slips off after the flight and becomes a drawstring tote.
• Kids’ play covers: A contained space keeps snacks and toys on the tray; Lusso Gear’s also holds a tablet at eye level.
• Single-use covers: Thin covers with an adhesive back, used once and replaced, like those in Seat Sitters’ travel kits.

What to look for

• Full coverage: A sleeve that wraps the underside as well as the top; an Emory-led study swabbed both the inside and outside of tray tables.
• Fit for your seat: Covers are sized for fold-down coach trays; Go-Be says its sleeves may not fit armrest trays in bulkhead seats.
• Easy washing: Machine-washable covers are simplest; Go-Be’s also go in the dryer, while Serenity’s are hand-wash, hang-dry.
• Weight and bulk: A plain Go-Be sleeve weighs 1 ounce; Serenity’s cover, with pockets, weighs 2.8 ounces.
• Secure pockets: Zippers, as on Lusso Gear’s adult cover, keep a passport or phone from sliding out.
• Fabric claims: Serenity says its fabric resists bacteria attaching; Go-Be says its fabric is the barrier, with no coating to wear off.

On the plane and on the trip

• Stowed for taxi: FAA rules require every seat-back tray table to be stowed for taxi, takeoff and landing; passengers must follow crew instructions.
• Seat-pocket weight: FAA guidance says seat-back pockets are built to restrain about 3 pounds.
• Takeoff and landing: Seat pockets are not approved stowage for carry-on items; the FAA says small, light items such as glasses or a phone may be fine.
• Crew has the last word: Flight attendants can still ask you to stow items during the flight, for example in turbulence.
• Wipes at security: TSA allows wet wipes and disinfecting wipes in carry-on and checked bags; the officer has the final say.
• Armrest trays: Bulkhead, exit-row and most business-class seats fold a tray out of the armrest; Go-Be says its sleeves may not fit those.
• Trains and buses: Go-Be says its sleeves also fit the tables on trains, ferries and buses.

Limits and care

• What swab tests found: In a 2015 Travelmath test, tray tables averaged 2,155 colony-forming units of bacteria per square inch, the most of any surface sampled; no fecal coliforms turned up.
• Germs can linger: In cabin-like conditions, Auburn University researchers found MRSA lived a week on seat-pocket cloth and E. coli four days on armrest material.
• Mostly harmless: An Emory-led study of 10 U.S. flights found cabin bacteria came mostly from human skin and mouths; tests for 18 respiratory viruses were all negative.
• Cleaning varies: Southwest says flight attendants tidy every aircraft between flights; in March 2026 Lufthansa tested lighter economy cleaning on about 20 short-haul routes.
• A barrier, not a cure: Go-Be says germs stay on the tray side of the fabric; wash the cover between trips.
• Fit has limits: Serenity says its cover fits most planes with pull-down trays, not every seat.

A short history

• July 2007: The earliest filing behind U.S. Patent 9,051,087, a sanitary tray cover with a personal pocket; granted in June 2015, it is the patent Airplane Pockets cites.
• September 2015: Travelmath publishes a swab test that names the tray table the dirtiest surface it sampled on planes and in airports.
• March 2018: The Emory-led FlyHealthy study, in PNAS, samples tray tables and other surfaces on 10 transcontinental flights.
• 2018: Go-Be’s founders come up with reusable tray sleeves over dinner in New York.
• March 2020: Delta photographs crews disinfecting tray tables, seat backs and screens with the same solution hospitals use.
• March 2024: Forum Brands is granted a U.S. patent for a two-piece tray cover: a spandex sleeve plus a prop-up tray.
• March 2026: Southwest says it may add cleaners at some airports; Lufthansa tests lighter economy cleaning on short-haul flights.
