At least one company is trying to capitalize on micro-nesting. In December, the London-based industrial design firm New Territory unveiled a product, called the Interspace, that is an upholstered seat back with foldout “wings.” Airlines could install this on premium economy seats, said Luke Miles, New Territory’s chief creative director, and someday provide better support for an economy passenger’s upper body and head.

If, when and how this product will be available to travelers is unclear. Until then, here are some products and hacks for settling into a tiny nest.

FOOT HAMMOCK So about that foot hammock Ms. Browning mentioned. She discovered these mesh slings on Qantas where they are installed on the Boeing 787 and the Airbus A380 to help travelers stretch out. Several companies sell them.

NECK WALLET Repurpose a trade show identity pouch, or purchase a neck wallet with a clear outside window and a larger zip-top pocket with space for a passport and phone. If you wear it from the time you leave the house until you arrive at your destination — and especially on the plane — you’ll always know where your phone is. Several varieties can be found online.

THE DO-EVERYTHING SCARF Many airlines have done away with blankets in economy. A washable, mid-weight scarf, at least 24 by 60 inches, can be used as a blanket, a travel pillow or a face mask. It can also act as an emergency towel or a make-it-yourself foot hammock.

SLEEP PRODUCTS Eye shades, ear plugs and neck pillows abound along with soft (albeit odd-looking) helmets that incorporate all three. Head harnesses strap the head to the seat’s back to prevent the neck-destroying bobblehead. Another option is to wear a hoodie on the plane and convert it to a neck pillow/eyeshade when it’s time to sleep. Find directions at many online sites including this one.

PORTABLE FOOD The decision to carry a reusable food container and utensils is between you and Mother Earth. Rigid containers take up more space in your carry-on but in addition to being green, they can relieve the anxiety of not knowing when you will eat next. Any travel lunch box with a good seal will do, or check out Black + Blum.
