When we moved in together, PT and I combined our pillows without thinking about it. We just put pillowcases on them and piled them on the bed. Two of them went to the bed in the furnished extra room that we rent out as often as we can (n.b. we have not used Airbnb yet!). Some were mine and some were his, but all of them—save for the one Ikea pillow I picked up at some point in the past seven years in New York—were of unknown provenance; and they were gross.
Membership in both NYRR and the coop is voluntary. The coop might have the best stuff, the freshest produce, the cheapest prices, and the largest selection of organic yogurts, but it is far from the only place in New York City to buy these items.
