Gas Piston vs Spring Murphy Bed Hardware: How to Choose the Right Lift System

A common question we hear is whether a Murphy Bed should use gas pistons or springs. If you’ve searched online, you’ve probably seen gas pistons positioned as the default “best” choice.

In practice, that advice often skips the most important detail: you’re not just choosing a lift mechanism. You’re choosing a complete wall bed system, and the frame matters.

Bottom line: if your wall bed will be used frequently, we generally recommend a spring lift system. In our experience, spring systems paired with a steel or aluminum frame offer stronger support, easier day-to-day operation, and simpler long-term serviceability.

Gas pistons can still be a fit in the right context, but they’re typically used on wood-frame Murphy Beds, and they behave differently over time.

So what’s actually different?

Gas piston systems (also called gas struts) use pressurized cylinders to counterbalance the bed’s weight. Spring systems use tensioned springs to do the same job. Both can work well when properly sized to the bed and mattress. Where people run into trouble is when they compare pistons vs springs as if they’re interchangeable parts. They’re not. The lift system is designed to work with the frame, the bed size, and the real mattress weight being used.

That’s why we start with the full setup: bed size, mattress weight, frame type, and how often the bed will be opened and closed. When a Murphy Bed feels “off,” it’s rarely because one mechanism is inherently bad. It’s usually because the system is mismatched to the weight it’s carrying.

From a homeowner’s perspective, the difference you’ll notice first is how the bed feels to operate. A spring system, when properly matched, tends to be lighter and easier to lift and lower, often with fingertip control. Gas pistons can require a heavier pull to open, and many people notice they feel heavier at the start of the lift when raising the bed off the floor. If the bed is used daily or nearly so, that ease-of-operation difference matters.

The second difference is what long-term ownership looks like. Over time, gas pistons can lose pressure, and when they do, the typical fix is to replace the piston. Springs can also change over time, but they generally lose tension, and in most cases only the spring(s) need to be replaced rather than the entire mechanism. Both are serviceable outcomes, but they’re not the same experience or cost pattern.

The third difference is structural. In our builds and experience, piston systems are typically used on wood-frame Murphy Beds. Spring systems are typically paired with steel or aluminum frames, which offer better weight support and overall strength. That frame difference is a big reason we prefer springs for frequent use: the lift and the structure are designed to work together.

What about vertical vs horizontal wall beds?

Orientation changes how the bed fits the room, but it doesn’t change the fundamentals of the lift decision. Vertical beds are the most common and are usually the simplest to plan for in terms of wall height and clearance. Horizontal beds can be a great solution under low ceilings, soffits, or windows, and often reduce how far the bed projects into the room when open. Either orientation can be designed with the right lift system. The key is still matching the system to bed size and mattress weight.

If you want a quick way to decide, here it is: if the bed will be used frequently, and you want the easiest lift and lower motion with strong, long-term support, springs are usually the better choice. If you’re considering a wood-frame wall bed and you’re confident your mattress weight will remain consistent, a piston system can be a fit, with the understanding that piston replacement is part of long-term ownership.
