Of course, you need one. Your house permitting, you can choose between floor lifts and installed or freestanding ceiling lifts. Vets here can tell you which ones the VA usually funds. Lots of vids on YouTube on what they each look like and how you use them.
Measurements to consider for a floor lift include the width of your narrowest hallway or doorway, the height/angle of any threshold that the lift would go over (like a bathroom), turning radius available wherever you would need to turn, etc. Also flooring type -- hopefully not thick carpet. The bigger the wheels the better if you have carpet, but they have to fit under the bed and around the wheelchair and any recliner(s) used. The lift legs go under the bed perpendicularly after you raise the bed if needed, and then you turn the cradle (the thing that holds the sling) to position your husband in bed before lowering the lift.
