Buying Guide – How to Choose the Best Keyboard Foam

Selecting the right keyboard foam involves considering material, size, and specific use case. This guide outlines the key factors to ensure you get the best acoustic upgrade for your setup.

Material Type

The material of the foam determines its durability and sound properties. Poron is widely preferred for its high-quality sound absorption and softness. It resists compression and provides a solid thock. EVA is also common and is more affordable, though it may not be as soft or long-lasting as Poron.

Look for high-quality materials like LE-20 or LE-32W Poron for the best results.

Thickness

Thickness affects how much cushioning and dampening the foam provides. Thinner foams like 1mm or 2mm are good for tight spaces under plates or switches. Thicker foams like 3mm are better for bottom case gaps where more volume filling is needed.

Choose thickness based on where you plan to install the foam in your keyboard.

Layout Compatibility

Foam sheets come in different sizes. Ensure the dimensions match your keyboard layout. Some products are universal cuttable sheets while others are pre-cut for specific layouts like 60% or 65%. Always check the product description for compatibility.

Verify the layout dimensions to avoid ordering foam that is too small or too large.

Adhesive vs Non-Adhesive

Some foams come with adhesive backing for easy installation while others rely on friction. Adhesive backing keeps the foam secure but may leave residue if removed. Non-adhesive options are cleaner but might shift over time.

Decide based on how permanent you want the mod to be.

Specific Component Focus

Some foams are designed for specific components like spacebars or switches. Spacebar pads target rattle from stabilizers. Switch pads target bottoming noise. Bottom case foam targets overall resonance. Choose the type that addresses your specific sound goals.

Determine if you need general bottom foam or specific component pads.

Ease of Installation

Installation can involve cutting the foam to size or pre-cut pieces. Pre-cut kits are easier to install but offer less flexibility. Cuttable sheets require precision but can fit any board. Tools like prying bars may be included.

Consider your technical comfort level when choosing between pre-cut and cuttable options.

Durability

Durability ensures the foam lasts over time without compressing too much. Materials with homogeneous cell structures resist deformation. This prevents the foam from losing its dampening properties after months of use.

Check product reviews for feedback on long-term durability.

Price

Prices range from budget-friendly spacebar pads to premium custom kits. Evaluate what you get for the price such as inclusion of tools or multiple layers. A higher price does not always mean better performance.

Compare the features and material quality against the price point.

How to Use and Care for Your Keyboard Foam

To install keyboard foam, you first need to disassemble your keyboard. Remove the keycaps and plate to access the internal PCB and bottom case. Clean the area of dust to ensure proper adhesion or fit. This process ensures the foam sits flush against the components.

If your foam requires cutting, use sharp scissors to trim it to the exact shape of your keyboard interior. Be careful not to cut into switch holes or mounting points. For sheets with dividing lines, snap or cut along these markers for precision. Take your time to ensure a perfect fit.

Once installed, reassemble the keyboard carefully ensuring no wires are pinched. If the foam is adhesive, press it firmly for a few seconds. Avoid exposing the foam to water or humidity during use to maintain its integrity. Regular cleaning of the keyboard exterior will help prolong the foam's life.
