What role does the structure of the duvet play? Stitched through squares, squares with baffles, channels?
Stitch through closed squares: The square structure stiffens the duvet and where it has been stitched through there is no filling, egual no isulation thus cold spots. The downs pressed into these squares, absorb little air, which also means little insulation. Furthermore the filling which cannot be plumped up will loose elasticity and volume in a short time. The shell (external cotton cover) and the filling will wear out quickly at points of friction with the body (feet, arms, etc …).
Square with baffles: Squares made with baffles does not compress the down filling, so the insulation is much better. But to fill the square duvet there is left a filling hole of Ø 6cm between all squares horisontally.
A filling tube is inserted and leaves an equal amount of filling in each square – but the filling hole is left open. Evidently is not possible to close it afterwards.
During the use of duvet, after a year or two the downs present in the central square, will slip into these open holes and glide towards the edges of the duvet, leaving the central area, where you sleep cold and empty. The shell (external cotton cover) and the filling will wear out quickly at points of friction with the body (feet, arms, etc …).
Our vertical channels duvets: are made with long tunnels (channels) with inner baffles (vertical walls) of varying height according to the amount of down filling in the duvets. Less down filling more vertical channels to assure that the filling remains well balanced.
The channel structure allows the goose down to expand (to loft) as much as possible, trapping air and thus creating proper insulation.The baffles permit a homogenous distribution of the downs along the channel structure and allows for internal circulation of air favouring constant warmth. The internal circolation of the down clusters ensure greather durability as the filling has no constant friction. . Furthermore the channel-like structure ensures an optimal adhesion to the body.

Dispelling a myth!
The channels duvet does not have a “good reputation” because of the duvet’s derivation from the duvet which was a simple sack of downs. In the beginning the channels were made too large so that the down filling was allowed an excessive range of motion, often causing the filling to move down to the feet and having all the weight at the end of bed the duvet tended to fall on the floor.
Danimarca s.r.l. Piumini Danesi ® ® pooq dene, wanted to believe in the potential of the channel structure, so we invested in research studies of structure and comfort, until we found a channel configuration that would prevent slippage of the down but still allowing an inner circle of air flows to ensure insulation together with homogeneous distribution of the filling.
You can in a simple way verify this when you air Danimarca s.r.l. Piumini Danesi ® pooq dene ® duvets; hanging the duvet with the channels vertically, you will see that the filling does not move.
Danimarca s.r.l. Piumini Danesi ® pooq dene ® has always used the channel structure. During the years the channel structure and filling have been adapted to the change of climate and housing from the seventies till now. The filling has been slightly reduced and consequently the number of channels increased.
