Designed to keep dosage confusion at bay, this compact product has seven large-capacity pill boxes marked with the days of the week for holding up to one-week of medication, with four large capacity cavities in each pill box.

The Puro headphones, which use durable, lightweight aluminum in the ear pieces and headband (not plastic), block out ambient noise (just the thing for use aboard an airplane), allow for Bluetooth or wired connectivity and have an 18-hour battery life (200 hours of standby). Crafted with 40mm dynamic drivers to provide, in Puro's words, "studio grade audio," the BT 2200 can be optimized to customize the sound with the use of a free Puro EQ ap. $79.99; www.purosound.com.Mogo Portable Upright Seat: This lightweight, collapsible seat goes where you go so you can sit relatively comfortably while those around you -- say at parades, outdoor free concerts and the like -- have to stand around getting tired and sore feet. Small enough (18 inches long retracted) and light enough (2.6 pounds) to fit easily in a backpack or tote bag, the Mogo extends through three telescoping sections to 37 inches in length (adjustable in 1-inch increments to accommodate most heights). A fiberglass-reinforced seat completes the picture. The Mogo, which is made from aluminum, comes with a reversible rubber base for grass or hard surfaces. The seat is designed to support up to 250 pounds. $99; www.focaluprightfurniture.com.
