As with many other things, there is a cost for convenience, and electric recliners are typically more expensive than manual recliners simply because of their motorized functions. They usually offer additional features, such as electric lifts and massage functions, which can cost even more.
Electric recliners require a power source to operate. Depending on where the outlets are located in your home, you may have a limited number of options for arranging the furniture. In addition to being unattractive, the cord can also pose a tripping hazard, so determine how you can hide the cord in your arrangement. In addition, if power goes out in your home, you can only use the chair in whatever position it was in when the power went out.
The electronic components in an electric recliner can malfunction, rendering certain functions useless until you can get the chair repaired. Repairing and maintaining the electronic components may require you to take the chair in to a service center, which can be costly and inconvenient. Depending on how old the chair is, it may be difficult to even obtain replacement parts.
Electric recliners are typically heavier and bulkier than manual recliners because of additional parts needed to accommodate motors and other electric options. The added bulk and weight may hamper your ability to move the chair around if you decide to change the arrangement.
