Incredibly easy to put together: just slide the back piece of the chair onto the glide rails and snap into place and screw in the 4 feet and you're done! I skipped the massage feature. The chair is relatively small and narrow, but definitely comfortable. Easy to sit upright or part way back to read or watch TV, as well as fully recline to take a nap. If you want something comfortable, inexpensive, sturdy with stress-free assembly, then this is highly recommended.
