RUBBERDOT
The humble rubber bumper, mastered — grip dots, feet, and non-slip fixes for every surface.
From sizing a rubber foot to its load and reading a durometer number to testing an adhesive bond, planning a grid of grip dots, and checking whether something will slide, RubberDot pairs free hands-on calculators with plain-spoken guides and a richly illustrated museum. Grip better, protect more.
Rubber Feet, Bumper & Non-Slip Calculators
Free tools for choosing and fitting protective and anti-slip hardware — foot & bumper size selector, durometer hardness guide, adhesive bond calculator, grip-dot spacing, furniture-foot load capacity, and an anti-slip estimator.
Rubber Foot & Bumper Size Selector
Size a foot or bumper to the load. Split the item's weight across its feet and get the minimum contact area and pad diameter that keeps the rubber — and your floor — within a safe pressure.
Durometer (Shore A/D) Hardness Guide
Turn a Shore A or Shore D number into something you can picture — a hardness category, everyday example materials, and the approximate equivalent on the other scale.
Adhesive Bond Strength vs Load Calculator
Check whether a stick-on bumper will hold. From the pad area, number of pads, adhesive strength, and load, get the holding force, the weight it carries, and a safety factor.
Grip-Dot Spacing & Coverage Calculator
Plan a grid of grip dots across an area — how many dots you need, the total rubber contact area, and the percentage of the surface covered.
Furniture-Foot Load-Capacity Calculator
Find how much a set of feet can safely carry, and the floor pressure a given weight produces — so you protect soft vinyl, laminate, and timber from dents.
Anti-Slip Friction & Coefficient Estimator
Estimate whether a rubber-footed object slides — the sideways force it resists, the steepest incline it stays put on, and the grip you'd need against a push.
Rubber & Materials Museum
Wander an immersive museum of the material world behind every bumper and foot — the long story of rubber from the tapped tree to the modern plant, the chemistry of vulcanization and polymers that made it tough, the fasteners and hardware that hold the built world together, and the wider field of materials science, each in its own gallery, so you can get to know how a humble grip dot connects to centuries of discovery.

How to Choose the Right Rubber Feet for Furniture
Rubber feet look simple, but the wrong size, height, or attachment leaves furniture wobbling, sliding, or marking the floor. A practical guide to picking feet by load, diameter, hardness, and how they fix on.
Understanding Durometer: What Shore Hardness Really Means
Durometer is the number that tells you how soft or hard a rubber is. Learn what Shore A and Shore D measure, how the scales overlap, and how to pick a hardness for feet, bumpers, seals, and wheels.
Adhesive vs Screw-In Bumpers: Which Should You Use?
Stick-on bumpers are quick and clean; screw-in and push-in bumpers are permanent and strong. Learn where each wins, why adhesive bumpers fall off, and how to pick the right fixing for the load.
How to Stop Furniture From Sliding on Hard Floors
Sofas that creep, chairs that skate, and rugs that wander all come down to friction. Learn why furniture slides on hard floors and the practical fixes — grippier feet, non-slip pads, and better weight distribution.
Protecting Floors From Scratches, Dents, and Marks
Furniture damages floors in three ways — scratching, denting, and marking. Learn how the right feet and pads prevent each one, why point-load pressure matters, and how to protect hardwood, laminate, vinyl, and tile.
Cabinet Door Bumpers: A Simple Guide to a Quieter Kitchen
Those tiny clear dots inside cabinet doors do more than silence a slam. Learn what door bumpers do, where to place them, which shape to choose, and how to fit them so they actually stay put.

Plain-language explainers on rubber and its history, the chemistry of polymers and vulcanization, the fasteners and hardware that fix things in place, and the materials science underneath it all — everything you need to dig deeper and fix things properly.
