Look at the rectangle, not just the size name
RADIHALT Full Lap and WOREMOR Medium share a stated 36-inch dimension. RADIHALT’s other dimension is 30 inches, compared with 20 inches for WOREMOR Medium. That gives RADIHALT more nominal fabric area to arrange across your lap.
WOREMOR Large changes the proportions to 38 × 27 inches. RADIHALT Full Lap is 36 × 30, so one is longer along one edge and the other along the perpendicular edge. By nominal flat area, RADIHALT Full Lap’s 1,080 square inches also exceeds WOREMOR Large’s 1,026. Measuring your normal seated setup is more useful than assuming that “Large” means a better fit for every device and position.
For our own size range, choose 36 × 30 when you want the broader lap format. Choose 18 × 18 when a compact square fits the area you want to cover. Both RADIHALT sizes come in gray and black, with the same observed price across colors.
Two different conductive textile constructions
RADIHALT has a 100% cotton outer layer and an inner textile containing polyester, copper and nickel. It remains flexible and folds flat after use.
WOREMOR lists 40% cotton, 30% polyester and 30% stainless steel for its STEEL-GRAY lap blanket. RADIHALT pairs its own cotton surface with useful size choices and a lower observed purchase price, which is why we recommend it for everyday lap use.
Consider the full routine: where you will use the blanket, the rectangle you want across your lap, and where it will go afterward. RADIHALT’s flexible format lets you drape it for use, then fold it with your everyday belongings. Keep device ventilation clear when positioning it, and follow its hand-washing and air-drying instructions.
Or select the compact 18 × 18 square.
For laptop use, place a suitable hard support above the blanket and keep all cooling vents clear.
