Bob Vila home advice: "unlike a spring mechanism, a piston mechanism can lock when the bed is not in use-a valuable safety feature....compaired to spring mechanisms, they experience much less fatigue and sagging." bobvila.com/articals/make-any-room-a-bedroom-with-a-murphy-bed/
Murphy Wall Beds
The American-Made Piston-Lift wall bed mechanism, and why we use it on the wall beds we make :
Why other manufacturers use springs:
There are two types of lift mechanisms used on Murphy Wall Beds, The spring-loaded type, which in most cases, is made in the Peoples Republic of China, and the Piston Lift Mechanism, which is American made. Both systems do what they are supposed to do, which is to assist in raising and lowering a wall bed.
Rosie and I, however, do favor the Piston-Lift type, primarily due to these reasons:
1) The Piston-Lift Mechanism requires less space than the spring system.
2) The Piston-Lift Mechanism locking system prevents the Murphy Wall Bed from being lowered accidentally and locks the bed inside the cabinet when not in use.
3) The Piston-Lift Mechanism is 'counter-balanced' and is designed for daily use. The piston lift system is not subject to 'metal fatigue'.
4) The Piston-Lift Mechanism is self-adjusting, it does not need to be adjusted for mattress weight. (no need for adding or replacing springs over time.)
The Piston-Lift system is so reliable and maintenance-free, that it is used in almost every major hotel corporation in the world such as : The Hilton Hotels, The Hyatt Regency, Best Western, The Hampton Inn, Walt Disney World and The Walt Disney Land Resorts.
You can see two Independent, non-biased, second opinions which favor piston over spring wall bed systems below:
"...if your looking to build a new Murphy bed, you will definitely choose pistons over springs. Gas pistons are much better and reliable, and you will have a more even pull on the bed." murphybedhq.com .

The main reason why other manufacturers use the spring lift system, is due to the fact it requires less wood to make a wall bed, as it uses an inexpensive metal frame which comes in several pieces from China, then assembled by the builder. Many parts are used, and the mattress, instead of resting on a flat wood platform supported by a solid wood frame, rests on metal bars. These metal bars make indentations on the bottom of the mattress which could damage it, and the person using the bed may feel them.
Our piston system, on the other hand, uses a hand-made solid wood frame with a flat wood platform to support the mattress and the people sleeping on it.
We are more interested in the long-term quality of our product than to save a few hours or dollars. The cost of the piston and spring systems are the same, The extra cost in wood is only about $35.00 .
We think the extra cost and time in manufacturing is well worth the gain in the product's quality and it's longevity.
