本書為倪其才重置當年的立體作品，請攝影師陳藝堂拍攝，並由他的女兒編輯結集。另亦收錄倪其才的雕塑素描。
倪其才當年的作品已不可考，只存在於他與家人的記憶裡。從女兒的印象中，約於1985-1995年間放學回家時，會在父母的臥室裡發現此等雕塑，形狀特殊，且無重複。
其妻不參與討論。
倪其才回憶起年輕時與朋友旅遊不小心住進情色旅館，床上就放了一個充滿性暗示的被子山，而啟發他此系列充滿性幻想的作品。
 
素描繪圖 
在女兒要求下，倪其才重置當年作品，並重新繪製了被子的素描作為準備，另外他說，他有先用衛生紙照著試摺過。
 
This is a collection of the temporary sculptures by Chi Tsai Ni. Ni re-arranges and sets them again according to his memory, when our photographer shoots them. Ni’s daughter edits the book, accompanied by Ni’s preliminary sketches. Chi Tsai Ni’s original works were gone. They only exist in the memory of his family members. As his daughter recalls, around 1989 - 1999, when returning home from school, she would find those sculptures lying in her parents’ bedroom. They came in weird shapes, and the shapes never repeated.
Ni’s wife does not participate in any discussion.
When re-making the sculpture series, Ni recalls the younger days when traveling with his friends, they lodged, by mistake, in a love motel. There on the bed was a pile of blanket-mountain giving a hint of sex. Ni’s own sculptures showed much the same sexy fantasies.
The Drawings
As requested by his daughter, Chi Tsai Ni re-makes the past sculptures, he draws new sketches for preparation. And he has used tissue paper to practice beforehand, he adds.
