Hello fellow DIYers: I am new to this group and I am sooooo glad I found you. My question concerns cutting a tempurpedic king size mattress into two so that I can make one half into an electric, adjustible bed. Has anyone cut a foam mattress with an electric knife? Are there any problems or tips to know about? Also, does anyone know of a source of good electric base mattress other than the tempurpedic ones? Thank you so much! Tahoe 93
