Difficulty of assembly depends on the specific adjustable bed. Some are easy to put together and require no tools. For example, GhostBed shows an assembly that takes only about two minutes. Others are more complicated, especially if they have smart or tech features that need to be hooked up.
Many retailers offer white glove delivery and in-home setup as part of your purchase. In this case, a delivery crew will bring the bed and set it up for you in the room of your choice. If you’d rather not assemble your adjustable bed on your own, check the retailer’s policy to find out if in-home setup is included as part of the cost.
