Flensted Mobiles UN17 Balance Mobile

Last updated: 5 November 2026

What it is, and what the seventeen stand for

A mobile is a balance problem solved in the air. Every arm has to counterweight every other one, and the whole thing has to stay in equilibrium while individual pieces are free to turn. Flensted's own description of their work is that the elements move constantly while the mobile as a whole holds its balance.

Rose & Rose designed this one in 2023. The seventeen shapes are the seventeen Sustainable Development Goals the UN adopted in 2015: no poverty, zero hunger, clean water, gender equality and the rest. The design does not label them. It is a set of coloured forms in balance, so the meaning sits behind the object rather than printed on it. That is a great deal better than a poster of the same idea.

Flensted, and 1953

Flensted have made mobiles in Denmark since 1953. The company's own account is that Christian Flensted made the first one to mark his daughter's christening, and that more than 200 designs have followed. It is now in its third generation as a family business and everything is still handmade in Denmark.

Flensted place themselves in a lineage on their own site, calling it "the same design tradition that gave us the PH lamp and The Egg". That is the mid-century Danish argument for designing ordinary domestic objects properly. A paper mobile is about as ordinary and domestic as the argument gets.

Size, materials and the assembly

It measures 65 by 65cm hung, which is larger than most people picture. Over a cot it will read as a canopy rather than an ornament. In a stairwell or a bay window it has room to turn.

The materials are tracing paper for the coloured elements, silicone, and stainless steel for the arms and threads. Tracing paper is why the colours glow when there is light behind them. It is also why the mobile belongs nowhere near a radiator, a bathroom, or a draught that will batter it against a wall.

It comes flat and you build it, which Kettle's Yard put at 20 to 30 minutes. That is a real half hour of threading and balancing, not a two-minute unwrap. Anybody buying it as a last-minute present should factor that in, and anybody giving it to a new parent should consider building it first.

The rest of the Flensted range at Kettle's Yard

The UN17 is the largest and the dearest of the seven Flensted mobiles Kettle's Yard stock. All seven were in stock on 6 September 2026.

The Niels Bohr at £65 is the other one to look at, because Bohr was Danish and the model is the atom he is famous for. The £18.50 postcard mobile is the version to buy as a stocking filler or a test of whether somebody likes mobiles at all.

Living with it, honestly

The ceiling. A mobile needs a hook and enough clear air below it that nobody walks into it. In a flat with 2.3m ceilings, a 65cm mobile is a decision about a whole corner of a room.

Paper and dust. Tracing paper elements collect dust and cannot be wiped. A soft brush or a hairdryer on cold is the honest answer, and neither is a job anybody enjoys.

The half hour. Assembly is the part people underestimate. It is threading and balancing, done once, and it is genuinely satisfying. It is also not something to attempt at eleven at night the day before a birthday.

Flensted UN17 mobile FAQs

What do the seventeen elements represent?

The seventeen United Nations Sustainable Development Goals, adopted in 2015. The mobile marks them as coloured forms in balance rather than labelling them.

How big is it?

65 by 65cm when hung, which is large enough to read as a feature rather than an ornament.

Does it need assembling?

Yes. It arrives flat and takes 20 to 30 minutes to put together and balance.

What is it made of?

Tracing paper, silicone and stainless steel. The paper is what makes the colours glow with light behind them, and it is also why the mobile should be kept away from damp and heat.

When was Flensted founded?

1953. Christian Flensted made the first mobile to mark his daughter's christening, and the company is now run by the third generation of the family. More than 200 designs have followed and all of them are still made by hand in Denmark.

How much does the UN17 Balance mobile cost?

£72 at Kettle's Yard, in stock on 6 September 2026. It is the largest of the seven Flensted mobiles they stock, which run down to £18.50.

Is it suitable over a cot?

It is designed as hanging art rather than as a nursery toy, and at 65cm it is big. Hang it where a child can look at it and not reach it, which usually means across the room rather than directly above.
