We were so excited to get are adjustable bed base.  We purchased the split king so we could adjust our beds to our own comfort.  Given our ages and medical issues this adjustable base has made a huge difference in our sleep and relaxation.  The base came in two boxes and was so easy to install.  The base is literally a plug and enjoy type of install.  We also like that the split king base comes with two remotes and adjustable leg height and  has soft sounding operation.
