Four separate heating zones spread warmth across the seat and back of this two-seat chair, sized as a large heating area for 2 adults rather than a single pad under one person. An upgraded heating pad behind them delivers quick and even heating, and dual switches mean each side runs independently, so one person can sit at high while the other stays low or off entirely. Three adjustable heat levels cover the range from about 100 to 104 degrees F on low, 104 to 113 on medium, and 113 to 122 on high, and power comes through a 5V 2A 10W USB port; running from a 10000 mAh power bank, that works out to roughly 6 hours on low, 4 on medium, and 3 on high. Underneath the fabric a sturdy metal frame handles up to 660 lbs, with X-support bracing the span to improve stability under that weight and non-slip foot pads keeping placement more secure on soft ground. The seat itself is a wide 42 in by 20.5 in set 17.5 in from the ground, backed by a 42-in by 20-in backrest, with the open chair measuring 58 in by 23.5 in by 37 in overall. Soft PP cotton fills the panels for full padded comfort and 600D Oxford fabric covers them for long-lasting outdoor use. Wine holders keep glasses close and upright, and multiple pockets organize gear and power banks instead of leaving them loose. The folding design saves time at both ends, and the 13.5-lb chair stores in the included bag at 10 in by 10 in by 38.5 in, and it comes in black or navy.
