The Cutting Table · a question, worked through
Is the corner floor cushion a quarter circle, and what does the size measure?
Folks lay a tape along the curve and then wonder why the numbers don't match. The size lives on the two straight sides that hug the walls.

The quick answer
The corner floor cushion is a quarter circle, and its listed size is the length of the two straight edges, the radius, not the curved front. The kids corner sofa cushion already measures 39 in (100 cm) along each straight side. Two quarter circles pushed together make a half circle against a flat wall; send a photo of the space and the workshop confirms the fit.

Measure the straight sides, never the curve
Neighbor, this one trips up a lot of good people. The corner floor cushion is a true quarter circle: two straight sides that meet at a right angle and tuck into the corner, and one rounded front that faces the room.
When a listing gives a size, it means those straight sides, the radius. Not the curve. The curved edge is always longer than either straight one, so a tape laid along it hands you a bigger number that matches nothing the workshop cut.
Measure out from the corner along each wall and that's your size. The corner floor cushion Atlas shows the shapes side by side, the quarter circle sizing Pattern goes deeper, and the glossary keeps a plain definition under corner floor cushion.
The next message: can two of them make a half circle?
Once the shape makes sense, the follow-up is nearly always about doubling up. Put two quarter circles together, straight edge to straight edge, and you get a half circle that sits flat against one wall. That makes a generous reading spot, and a soft landing for little ones who haven't mastered stopping. Kids and dogs are the real quality control.
Send a photo of the wall and floor you have in mind, and the workshop confirms it will work before you order. Torn between lavender, indigo and blue? Ask, and the shop sends photos of those colors side by side, since the three sit close together. Ideas for the rest of the room live in the playroom corner Concept Sketch.
How wide is the wall you're picturing?
A 39-inch question with a happy answer
A buyer in the US measured a playroom and asked whether the kids corner sofa cushion could be made with 39-inch straight sides to fit. It already is: 39 in (100 cm) along each straight edge, right off the listing. Sometimes the size you need is sitting there waiting, and all it takes is knowing which edges the number belongs to.
Two quarter-circle corner cushions pushed together make a half circle against a flat wall, and the reading spot doubles in size.
