A spa cover lifter comprising opposing left and right side arm supports spaced apart to receive opposing left and right cover side surfaces between the same. Each side arm support has an upper end adapted to rotatably support a portion of the spa cover and an opposing lower end. Each side arm support is rotatably mounted to a spa side. Extending from the right side arm support, around the back spa side, to the opposing left side arm support is a lower linking member having opposing ends spaced apart to pivotally attach to the respective spaced apart left and right side arm supports. The linking member can pivot relative to the side arms, about a substantially horizontal axis to define a linking member pivot angle which is the angle between each side arm support and the linking member. The pivotal attachment point of the lower linking member to the respective side arm support is adjacent the respective lower end thereof. To maintain the relative angle between each side arm support and the linking member, an adjustable bracing extends between each side arm support and the linking member. The relative position between each side arm support and the linking member is adjustable.
