In order to amplify safety and comfort, we have made these efforts: enlarge the thick headrest for a more comfortable lying experience, thicken and thicken the frame to make it more stable and stronger in terms of load-bearing capacity, lengthen the solid wood armrest, which is more delicate and smooth to the touch, and the gear adjustment buckle can be adjusted up to 165°, so you can choose a more comfortable angle for sitting and lying down, and turn into a flexible remote control that will not roll over and take a rest in the wild, thicken the preferred link to do a good job in every step of the foundation tamping, and thicken and thicken the horizontal brace to make multiple insurances for your safety; 180°Foldable and stored, easy to handle and easy to carry. Committed to bringing you the best outdoor experience.
