back scratch

Listings describe extendable manual back scratchers made from stainless steel and wood — for example, one listing specifies 77% 201 stainless steel and 23% Schima superba wood — and note the materials are non-toxic.

Many massagers use vibration motors and built-in heating elements. Several offer multiple modes and adjustable intensity, kneading nodes with bi-directional rotation, and typically plug in via AC/DC adapters. Some listings also note battery or USB power where specified.

Posture correctors in the results are described as aligning the upper back, spine, and shoulders to reduce slouching and ease back or shoulder discomfort. They use breathable, lightweight materials with adjustable shoulder straps and a wide waist belt for a customizable fit and easy wear.

Many cushions and pads are described as portable and lightweight, designed to fit on recliners or office chairs and often include straps to secure them. A few listings also include car or DC adapters for in-car or travel use.
