Glass Side Tables: Edge Finish Types and UK Safety Standard Compliance

The edge of a glass side table is the part of it most likely to be touched, knocked and judged, and it is also the part that tells you most about how the piece was made. A properly finished edge is smooth to the hand along its whole length, consistent in width, and free of the sharp arris that raw cut glass leaves behind.

On safety, the position in the UK is narrower than most product descriptions imply. BS EN 12150 sets out requirements for thermally toughened soda lime silicate safety glass, and toughened glass is the material used in reputable glass furniture because it breaks into small blunt fragments rather than shards. Furniture itself is not glazing, so it sits under general product safety law rather than under building glazing regulations, and the practical assurance a buyer should look for is toughened glass with a properly worked edge.

Key findings at a glance

• Edge finish is a manufacturing quality signal as much as an aesthetic choice: a ground and polished edge takes more process time than a simple arrised one.
• BS EN 12150 covers thermally toughened soda lime silicate safety glass, which is the material specification that matters for glass furniture.
• Building glazing standards such as BS EN 12600, which classifies impact performance for flat glass in buildings, apply to glazing rather than to furniture, so they should not be quoted as furniture compliance.
• Toughened glass cannot be cut, drilled or reworked after toughening, so all edge work is done before the glass is heat treated.
• Toughened glass is vulnerable at the edge rather than across the face, which is why chips at the perimeter matter more than scratches in the middle.
• Thicker glass allows a wider bevel or a deeper polish, so edge style and glass thickness are linked decisions.
• In homes with young children, a rounded corner radius does more for safety in practice than the edge profile does.

The edge finishes you will actually encounter

There are a handful of finishes in common use, and the vocabulary is worth knowing because it is used inconsistently in retail listings.

An arrised edge, sometimes called a seamed edge, has had the sharp corner removed by a light grind. It is safe to handle but it is not decorative, and it is generally used where the edge will be hidden inside a frame. A flat ground edge is squared and matt, smooth to the touch but not clear. A flat polished edge takes the same profile and works it until it is optically clear, so light passes through the perimeter rather than scattering. A pencil edge is rounded in profile, either ground or polished, and is the most forgiving to knock against. A bevelled edge is cut at an angle around the perimeter, producing the band of refracted light that gives traditional glass furniture its character, and a mitred edge is a steeper version used where two panels meet.

Each has a place. A pencil polished edge is our usual recommendation for a piece that will sit beside seating and be brushed past, while a bevel suits a table intended to be a decorative object in its own right. Across our modern glass side tables UK range, the finish is chosen for where the piece stands rather than for cost alone.

What toughening actually changes

Toughened glass is heated and then rapidly cooled, which puts the surface into compression and the core into tension. The result is considerably stronger than annealed glass of the same thickness, and it fails differently: rather than breaking into long sharp pieces, it fragments into small blunt granules. That failure mode is the reason it is used in furniture, and it is the single most important specification to confirm before buying.

There is an important consequence for the edge. Because the stresses are locked in during toughening, the glass cannot be cut, drilled or ground afterwards. Every hole, curve, bevel and polish must be finished first. That is why a chip in the edge of a toughened panel is not repairable and why a knocked edge is a genuine risk to the whole panel, while a light scratch on the face is usually cosmetic.

Standards, and what they do and do not cover

It is common to see furniture described as meeting glazing standards it has nothing to do with. To be precise about it: BS EN 12150 concerns thermally toughened soda lime silicate safety glass as a material, and BS EN 12600 provides a pendulum impact test classification for flat glass used in buildings. Building Regulations address critical locations for glazing in doors, screens and windows. Those requirements govern the built fabric, not a side table.

Furniture in the UK falls under general product safety requirements, which oblige products placed on the market to be safe in normal and reasonably foreseeable use. There is no single number to quote here, and we will not invent one. The practical checks are the ones that can be verified in the room: confirm the glass is toughened, confirm the edge has been worked rather than left raw, confirm the corners are radiused or otherwise treated, and confirm the panel is fixed or seated so it cannot slide off its support.

Specification table: matching edge finish to use

The table below sets out how we match edge finishes to position and glass thickness. These are specification conventions rather than measured statistics.

Edge finish	Profile	Typical glass thickness	Best position	Handling note
Arrised or seamed	Sharp corner lightly removed, matt	4 mm to 8 mm	Inside a metal or timber frame	Safe to touch but visually unfinished when exposed
Flat ground	Square edge, smooth and matt	6 mm to 10 mm	Lower shelves and concealed tiers	Shows dust along the ground band
Flat polished	Square edge, optically clear	8 mm to 12 mm	Exposed top surfaces	Corners remain the most vulnerable point
Pencil polished	Rounded, clear	8 mm to 12 mm	Beside sofas and in circulation routes	Most forgiving profile if knocked
Bevelled	Angled band around the perimeter	10 mm and above	Feature tables and display pieces	Needs thickness to carry the bevel width

Living with glass in a British home

Glass earns its place in small rooms for the same reason mirrors do: it occupies volume without occupying the eye. In a narrow terraced living room, a glass table lets the rug and the floor read continuously beneath it, which keeps the space visually open. That is the strongest practical argument for the material, and it is why modern glass coffee tables UK remain a standard answer to a room that is short on floor area.

The maintenance reality is straightforward. Glass shows marks immediately and cleans completely, which is the opposite of most furniture finishes. A soft cloth and a non abrasive cleaner is sufficient, and abrasive pads should be avoided because they will haze a polished edge. Coasters matter less for damage than for appearance, since glass is unaffected by heat rings but shows water marks clearly.

Placement is where most problems start. Keep glass out of primary walking routes where possible, particularly where a corner sits at shin or knee height, and avoid positions where a table can be pushed against a hard object such as a radiator or a skirting nosing. In homes with small children we suggest rounded corners and a low profile piece, or a nest arrangement that can be reduced when the room is busy. A set of modern nest of tables UK works well here, because the smaller tables can be put away entirely.

What this means for UK homes

Ask one question before style: is the glass toughened? If a seller cannot confirm it, treat that as the answer.

Run a hand along the whole edge, including the underside of the perimeter. A finished edge feels consistent. A raw or partially worked edge will catch.

Match the finish to the position rather than to the photograph. A bevel that looks striking on a display table is a poor choice for a table wedged between a sofa arm and a wall.

Inspect the corners on delivery and again if the piece is ever moved. Edge and corner chips are where toughened panels fail, and a chipped panel should be taken out of use rather than monitored.

Finally, check the fixing. The panel should be seated in a rebate, held by suction pads or clamped by the frame so it cannot slide. Our modern glass end tables UK are built around that principle of a secured panel with a fully worked edge, and the wider collection can be seen at Furniture in Fashion.

Methodology

This 2026 report was compiled from our editorial assessment as a UK furniture retailer, from standard glass furniture specification and edge working conventions, and from named published standards where they genuinely apply, specifically BS EN 12150 for thermally toughened soda lime silicate safety glass, BS EN 12600 for impact classification of flat glass in buildings, and Building Regulations provisions relating to glazing in critical locations. We have been explicit that the latter two govern building glazing rather than furniture. The report contains no test results of our own and no proprietary sales, pricing or customer data, and no survey fieldwork, panel or academic partnership was involved.

Frequently asked questions

What is the safest edge finish on a glass side table?

A pencil polished edge is the most forgiving in daily use because the profile is rounded rather than square. For homes with small children, however, the corner radius of the panel matters more than the edge profile itself.

Is all glass furniture made from toughened glass?

It should be, but it is worth confirming rather than assuming. Toughened glass is stronger than annealed glass of the same thickness and breaks into small blunt granules rather than sharp shards, which is the property that makes it appropriate for furniture.

Which UK standard applies to glass furniture?

BS EN 12150 is the relevant material standard for thermally toughened safety glass. Building glazing standards and Building Regulations glazing provisions apply to windows, doors and screens rather than to furniture, which sits under general product safety requirements.

Can a chipped glass table edge be repaired?

No. Toughened glass cannot be cut, ground or reworked after heat treatment, so edge chips cannot be polished out. A chipped edge weakens the panel and the piece should be taken out of use.

How thick should the glass on a side table be?

For an exposed top, 8 mm to 12 mm is the usual range, with thicker glass required where a bevel is wanted because the bevel needs depth to be cut into. Thinner glass is normally used only where the panel is supported inside a frame.
