A bed is not a real bed without a bed frame. True, a mattress on the floor can substitute for a bed. But it is only a temporary solution.
An essential part of adjustable beds is their bed frame. Adjustable beds require a sturdy, well-built frame to function as intended. A weak, marginal bed frame can not support the motors and other movable parts of the bed for any length of time.
Good adjustable bed frames are made from heavy-duty steel and steel rails. A well thought out adjustable bed frame is capable of handling heavy loads for many years without catastrophic failures.
Most failures are caused by the electromotors that move the panels of the bed into position. High-quality electromotors are expensive. And so are other parts of the internal workings of an adjustable bed. These parts are well hidden away under the deck on which the mattress rests. But out of the way is not necessarily out of consideration at the time of purchase. Quality mechanical and electronic parts are expensive.
The more electronics an adjustable bed offers, the more electronic parts are integrated into the bed design. That explains why beds with many frills are more failure prone than basic adjustable beds.
The price of adjustable beds is for the bed frame and the attached mechanical and electronic parts only. It does not include the price for the actual mattress used on the bed. That is a separate and additional price.
Prices for adjustable beds vary by bed size and frills. A simple single bed can cost from an all-time low of $ 100 to $ 1,000. The low-ball single for $ 100 surprisingly has an owner satisfaction rating of 89 percent.
However, most serious adjustable beds cost between $ 700 and $ 2,000. The best go for between $ 2,000 and $ 3,000.
That is a big step up from a simple conventional bed frame. But it makes up for the price with improved quality of sleep and some health benefits.
