The Trinity (Fr Blackout) is a made-to-measure roller blind sold by 247 Blinds in 25 colourways, with prices starting from £10.26. The "Fr" designation in the name suggests a fire-retardant fabric treatment, which makes it a range to consider where fabric specification matters alongside light control.

Who it suits

The blackout opacity rating makes the Trinity most at home in bedrooms, nurseries, and children's rooms where early-morning light is genuinely disruptive. A blackout fabric blocks light through the material itself - though, as with any roller blind, some light will still enter around the edges of the blind. For complete darkness, combine with side channels or a perfect-fit fitting if your windows allow it.

The FR designation - implying fire-retardant treatment - could make this worth looking at for rooms where that specification is relevant, such as rental properties, homes with open-plan staircases, or where a landlord or insurer specifies fire-rated furnishings. Confirm the specific fire-rating standard with 247 Blinds before ordering if that is a deciding factor.

The range is less suited to kitchens and bathrooms, where a PVC or moisture-resistant fabric would be a more practical choice. It would also be an unusual choice for a living room unless daytime darkening is specifically wanted - a light-filtering or dimout roller would give more versatility in a lounge or sitting room.

The colours

25 colours available

The five colourways split neatly into blue-toned and purple-toned options. Chickadee sits at the cooler, more neutral end - likely a blue-grey that would read as understated in most rooms. Kingfisher and Blue Depths are the more assertive blues, with Blue Depths suggesting a deep navy or rich oceanic tone. Empress and Venetian Purple sit in the warmer purple register, with Venetian Purple likely the most saturated of the five.

This is not a neutral palette. If you need an off-white, cream, or greige roller to disappear into the décor, this range is not it. The Trinity is for rooms where the blind is allowed to be a colour statement - a child's bedroom, a media room, or a study with a defined colour scheme. The concentrated palette means there are five genuine choices rather than shades of the same safe tone, which is an honest approach to a limited range.

The from-price puts this at the entry-level end of the made-to-measure market. As with all made-to-measure rollers, the price rises as width and drop increase - the widget above shows what your specific dimensions would cost. At smaller sizes the range is accessible; at larger dimensions it moves toward the mid-range of the market, which is typical for this type of product.

How it compares

Within 247 Blinds' own roller range, there will be other blackout options across a wider neutral palette if the bold colours here don't suit your room. If thermal performance matters more than blackout alone, a cellular or honeycomb blind would outperform any roller fabric in that regard - the sealed air pockets in a cellular blind insulate in a way no flat roller can match.

For children's rooms in particular, worth confirming the operation type: a cordless or wand-operated version removes the cord-safety concern that applies to any room with young children. UK regulations require cord-safe blinds for domestic sale, but it is still worth verifying the specific mechanism before ordering.

Fitting and operation

Roller blinds of this type typically fit either inside the recess or face-fixed to the wall above the window. Inside the recess gives the cleaner look; face-fixing is the better choice if the recess is too shallow for the blind mechanism or if you want to cover as much of the frame as possible to reduce edge-light. 247 Blinds will ask for your preferred fitting method during the ordering process.
