I expected to be stiff after 12 hours in economy. Instead? No soreness. No pain. Just arrived ready to go. That extra cushioning made the difference between suffering and sleeping. Highly recommend.

Packs easy
01
Packs down to about 12 × 14 inches and under 1 lb. Goes in your carry-on or under the seat in front.
Cap off, then inflate
02
Pull the inflate cap fully off first — this is the step people miss. Then squeeze the built-in pump about 30 to 40 times, which is where most people find it comfortable. Press the cap firmly back on to seal it. No separate pump, no mouth inflation.
Dial it in
03
Sit down, then adjust. Too firm? Press the red release button to let air out. Want more support? A few more pumps. Both without getting up. Most people settle around 60–80% full rather than fully inflated.

Finally, a flight that didn't wreck me
Zero padding on my backside means every flight is agony. Not anymore. San Jose to Hawaii used to ruin me. Now? Nothing. No pain, no numbness. Relvie is a lifesaver. I literally won't fly without it.

My tailbone finally stopped screaming
Long flights used to destroy me. Nine hours of grinding pain, arriving too sore to function. With Relvie, I landed feeling rested—no pain, no stiffness. First time in years I didn't need a recovery day after flying.

I won't board a plane without it
Economy seats feel like wooden benches now. Relvie folds small and still gives me the support I need for any flight. I've used it on 6-hour flights, 12-hour flights, even at my desk. Genuinely the best purchase I've made for travel.

Made a 12-hour flight actually bearable
I expected to be destroyed after 12 hours in economy. Instead? No soreness. No pain. Just arrived ready to go. That extra cushioning made the difference between suffering and sleeping. Highly recommend.

★★★★★
Way easier than I expected
I almost didn't buy this because I hate dealing with pumps and blowing things up. But inflating Relvie takes maybe 60 seconds—just press the built-in button with your hand. No tubes, no huffing and puffing. Simple, quick, and hygienic.

FREQUENTLY ASKED QUESTIONS
EVERYTHING YOU
WANT TO KNOW.
Nearly always because the inflate cap is still on, so the pump just recirculates air inside the cushion instead of drawing new air in. Pull the cap fully off, then pump. If it still won't inflate, email hello@shoprelvie.com and we'll make it right.
Yes — provided the inflate cap is pressed firmly back on after you inflate. Left open, air escapes each time you shift your weight, which is the usual reason a cushion goes soft mid-flight. Sealed, it holds pressure for the entire flight.
That's where a lot of people get the most use. Road trips, trains, bleachers at sports games, festival chairs, office chairs if you're stuck at a desk all day. Anywhere you'd otherwise be sitting on something hard for hours. Plenty of people break theirs in at home or in the car first — worth doing, so you have the valve sorted before you're working it out in a plane seat.
That's the whole point. Standard plane seats compress your sciatic nerve and cut off circulation after 2-3 hours, which is why you get the numbness, aches, and hot spots. Relvie's air cells redistribute your weight evenly so blood keeps flowing and pressure points never build up. Same principle as hospital-grade pressure relief cushions, just portable.
Under a minute. Pull it out of the pouch, take the inflate cap fully off, and press the built-in pump about 30 to 40 times. That is where most people find it comfortable — around 60 presses takes it to full, which is firmer than most people want. No blowing into it with your mouth, no separate pump to carry.
No. It's designed to sit low and spread pressure, not act as a booster. Most people inflate to around 2 inches at medium firmness. You can also run it softer if you're tall or want a lower profile.
Yes. Folded into its carry pouch it is about 11.8 by 13.8 inches and 130mm thick — roughly a folded sweater. It slides into any standard carry-on, overhead bin or under-seat bag, and weighs under 1 lb.
Yes. It's a personal comfort item, same category as a neck pillow, and welcome on every major carrier including Qantas, Emirates, Singapore Airlines, British Airways, United, Delta, and Air New Zealand.
You have 60 days. Take it on a real flight, and if it's not for you, start a return yourself at shoprelvie.com/apps/parcelpanel-returns — it goes to our US warehouse, not overseas, though return postage is yours. Separately, a 1-year warranty from your delivery date covers the valve, seams and air cells if anything fails.
Orders ship within 24-48 hours. Most orders arrive within 7-12 days, often sooner.
Pull it out of the pouch once you're seated, take the inflate cap off, pump it up, then press the cap back on to seal it. Place it on your seat and sit down. Deflate and pack it back down before you get off.

Questions before you buy
Can I use it on an airplane seat?
It is intended as an added seat cushion for travel. Compare its footprint with your seat, follow the airline’s rules and crew instructions, and make sure the cushion does not interfere with your seat belt or secure seating.
How do I adjust it if my seat feels too firm?
Use the built-in pump to add air, then release a little air if you prefer a softer feel. Adjust gradually while checking your seating position. More air is not automatically more comfortable.
What comes with the single cushion?
The single-cushion offer includes one cushion and one eye mask. A travel carry case is an optional paid add-on for that offer.
What comes with the two-cushion offer?
The two-cushion offer shown on this page includes two cushions, two carry cases, two eye masks and the travel-hacks ebook. Select that offer on the page; the catalog’s single-unit price does not represent the two-cushion bundle.
Is this a foam cushion or a back-support pillow?
It uses adjustable air cushioning under your seat, rather than a foam filling. For a separate inflatable back-support pillow, see the Relvie Travel Lumbar Cushion.
Does it guarantee pain relief?
Comfort depends on your body, seat and how you adjust the cushion. This is a comfort accessory, not a treatment or a guarantee of pain relief.
How do I clean and store it?
Follow the care instructions supplied with the cushion. Deflate it for packing and keep it away from sharp objects. Do not assume it is machine washable.
What are the return and warranty terms?
The return window is 60 days after delivery under our return policy. The Air Cell parts warranty covers defects in the valves, seams and air cells for one year; damage from misuse is excluded. Check the linked policies for the full terms.
