Can You Use a Mattress Pad on a Murphy Bed?

Why Thickness Matters for Folding

A Murphy bed folds into a cabinet or against a wall, so the mattress and anything on top of it must fit within the space the maker designed. The bed's mechanism and cabinet depth are built around a specific mattress height. Adding a thick mattress pad can push the total height beyond that limit, which may prevent the bed from closing fully or put stress on the lift system.

Most Murphy beds, including those from Wilding Wallbeds, are designed for mattresses up to a certain thickness. For example, Wilding's Murphy Desk Bed page notes that the mattress sits at approximately 32 inches from the floor when using a 10-inch mattress. That figure tells you the bed is set up for a mattress around that height. A pad that adds several inches could exceed the intended clearance.

The safest approach is to read the listing or the maker's page for the maximum mattress height. If the bed comes with a mattress, like the tri-fold mattresses included with Wilding's Murphy Cabinet Beds, the pad must not add so much bulk that the folded bed no longer fits. A thin pad, usually under an inch thick, is the most reliable choice. For more on choosing a bed that fits your space, see our guide to the best Murphy beds.

• Check the maker's stated maximum mattress height before buying a pad.
• Choose a pad that is thin, typically less than an inch thick.
• Avoid thick pillow-top pads or multiple layers of padding.
• If the bed includes a mattress, confirm the pad does not exceed the combined height limit.

Types of Pads That Work Well

Not all mattress pads are the same. A quilted cotton pad is usually thin and flexible, making it a good fit for a Murphy bed. A memory foam topper, even a thin one, adds more height and may compress unevenly when the bed is folded. A fitted mattress protector, which is essentially a thin cover, adds very little bulk and is often the best option if you want protection without changing the feel of the mattress.

Some Murphy beds, like the cabinet beds from Night and Day Furniture, come with tri-fold mattresses that are designed to fold with the bed. In that case, a pad must not interfere with the folding action. A pad that is too thick could cause the mattress to bulge or the cabinet doors to not close properly.

When you shop, look for pads labeled as low-profile or thin. Avoid pads with deep quilting or thick foam layers. A pad that is less than an inch thick is generally safe, but you should still verify it against the bed's clearance. If you are considering a cabinet bed, our cabinet bed guide can help you compare options.

• Quilted cotton pads: thin, breathable, and flexible.
• Fitted mattress protectors: minimal bulk, good for protection.
• Thin memory foam toppers: use only if the bed's clearance allows.
• Avoid thick pillow-top pads and multiple layers.

How to Check Clearance Before Buying

Before you buy a mattress pad, you need to know the bed's maximum mattress height. This information is usually in the product listing or on the maker's page. For example, Wilding Wallbeds lists the dimensions of their Murphy Desk Bed, including the cabinet depth, which gives you an idea of the space available. The cabinet depth for that bed is 21 inches, and the mattress sits at 32 inches from the floor with a 10-inch mattress.

If the bed does not state a maximum mattress height, contact the maker or seller. You can also measure the space inside the cabinet when the bed is closed, but that is only possible if you already own the bed. For a new purchase, the listing is your best source.

Once you know the maximum height, subtract the mattress height to see how much room is left for a pad. For example, if the bed allows a 12-inch mattress and you have a 10-inch mattress, you have 2 inches of clearance. A thin pad under an inch thick would fit, but a thick topper might not. For more on measuring your room, see our guide on measuring for a Murphy bed.

• Find the maximum mattress height in the listing or maker's page.
• Measure your mattress height if you already own it.
• Subtract the mattress height from the maximum to find the pad allowance.
• When in doubt, choose a thinner pad.

How a Pad Affects Folding

When a Murphy bed folds up, the mattress bends or stands on end. A pad that is too thick can create a lump or add pressure on the fold line, which may damage the mattress or the pad over time. The mechanism, whether it is a spring lift or a piston lift, is designed to handle a certain weight and size. Adding bulk can make the bed harder to lift or lower, even if the weight is within the limit.

Wilding Wallbeds uses spring lift mechanisms in their Studio Series and piston lifts in their HomeFront Series. Both are rated for specific weights, but the height of the mattress and pad is just as important as the weight. A pad that is too thick can prevent the bed from locking into the closed position, which is a safety concern.

To avoid problems, always follow the maker's instructions for the maximum mattress height. If the bed comes with a mattress, like the tri-fold mattresses from Wilding's Cabinet Beds, use a pad that is designed to be thin and flexible. A pad that stays in place with elastic corners is better than a loose pad that might shift during folding. For more on how the mechanism works, see our article on springs vs pistons.

What to Look for in a Pad

When you are choosing a mattress pad for a Murphy bed, focus on three things: thickness, flexibility, and fit. Thickness is the most important, as it determines whether the bed will fold properly. Flexibility matters because a stiff pad may not bend with the mattress. Fit is about keeping the pad in place, so look for a fitted style with deep pockets or elastic corners.

A pad with a smooth surface is easier to manage than one with a thick quilted pattern. Some pads are machine washable, which is a plus for guest rooms. You might also consider a waterproof pad if you want to protect the mattress from spills, but make sure it is thin.

If you are buying a Murphy bed that includes a mattress, check whether the maker recommends a specific type of pad. For example, Wilding's mattress page lists several foam and innerspring options, but it does not mention pads. In that case, a thin, universal pad is a safe bet. For beds with a desk, see our desk bed guide for more considerations.

• Thickness: under an inch is safest.
• Flexibility: choose a pad that bends easily.
• Fit: use a fitted style with elastic corners.
• Care: look for machine-washable options for easy cleaning.

Common Mistakes to Avoid

One common mistake is buying a thick memory foam topper without checking the bed's clearance. Memory foam is heavy and adds height, which can cause the bed to not close properly. Another mistake is using multiple layers, like a pad plus a topper, which quickly exceeds the height limit.

Some people also forget that the pad adds to the mattress height, not just the comfort. Even a 2-inch pad can be too much if the bed is already at its maximum. Always measure or check the specs before you buy.

Finally, do not assume that a pad is safe just because it is soft. The bed's mechanism is engineered for a specific mattress size and height. A pad that is too thick can strain the lift system, which may void the warranty. Follow the maker's guidance to keep your bed working as intended. If you are considering a DIY kit, our kit guide can help you understand the specifications.

What to pick for your situation

Questions

Can I use a memory foam topper on a Murphy bed?

You can, but only if the topper is thin and the bed's clearance allows it. Memory foam adds height and weight, so check the maker's maximum mattress height first. A topper thicker than an inch is usually too much.

Will a mattress pad prevent the bed from folding?

A thick pad can prevent the bed from folding completely, which may damage the mechanism or the cabinet. A thin pad, under an inch, is unlikely to cause problems if the bed is not already at its height limit.

Do Murphy beds come with a mattress pad?

Most Murphy beds do not include a pad. Some cabinet beds, like those from Wilding Wallbeds, come with a tri-fold mattress, but the pad is separate. You can add a thin pad as long as it fits within the clearance.

What is the best type of pad for a Murphy bed?

A thin quilted cotton pad or a fitted mattress protector is best. These add minimal bulk and are flexible enough to fold with the bed. Avoid thick foam toppers and pillow-top pads.

How do I know if a pad is too thick?

Check the bed's maximum mattress height in the listing or maker's page. Subtract your mattress height from that number. If the pad is thicker than the remaining space, it is too thick.
