Serious answer There are a couple of factors that mike it unlikely . You don ' t have an Ikea couch . If you don ' t go for Ikea you want something unique so you will avoid what others already have manufacturers probably lure you in with new designs every year . a couch more expensive than Ikeas lasts a long time , some even move through the generations . This means the production date of the couches of people is spread a lot and enhances tho previously mentioned factor . the number of couches per capita is not so high . Some people have non , others still not as many couches as people in flat . Those who do have several couches might have the same couch twice to match the design . For our statistics this is the same as a single couch .
