Bella is a double roller - also called a day-and-night or vision blind - sold by two UK retailers, Blinds By Post and Swift Direct Blinds. A double roller layers two striped fabrics that slide over each other, so you can line up the solid bands for privacy and shade, the sheer bands for an open view, or anywhere in between to set the light. Both retailers list Bella at a closely matched from-price, so it is very likely the same wholesale fabric cut to order by each.

Because the mechanism and the cloth are shared, the differences come down to fittings, colour and the price at your size. Both retailers offer a no-drill option, which suits a uPVC window or a rented home. With a day-and-night blind the striped bands are part of the look as well as the function, so check the colour range each shop carries within the Bella family if a particular shade is the draw.

A double roller carries more fabric and mechanism than a plain roller, and its price climbs with width and drop, so the smallest-size from-price is not a reliable guide to your window. Enter your exact measurements into the pricer below and compare both retailers' totals for the size you need.

We match these on the shared name and a price that scales the same way across window sizes, not an independent inspection, so treat it as likely the same fabric rather than confirmed. Construction, exact colourway and fitting can vary between retailers - check the specification at each before buying.
