An aircraft seat may include an upper aircraft seat assembly (126), a lower aircraft seat assembly (128), and a frame actuation assembly (110) configured to actuate the upper aircraft seat assembly (126) relative to the lower aircraft seat assembly (128). The lower aircraft seat assembly (128) may include at least one spring (202) coupled to a foundation (108) with a sloped actuation surface configured to cause the upper aircraft seat assembly (126) to be at a decreased height when in a bed position. The compressing of the at least one spring (202) may be configured to counterbalance a load within the aircraft seat and generate a controlled actuation of the upper aircraft seat assembly (126) from an upright position to the bed position. A return force provided by the at least one spring (202) may assist the frame actuation assembly (110) during actuation of the upper aircraft seat assembly (126) from the decreased height of the bed position to the upright position.
