Three piece suite  

Where are you located?  It looks kind of American to me, except for the Pirelli webbing straps.  The finish looks like lacquer, which would be unusual (but not unheard of) for Danish teak.  It might even be tinted lacquer to make it look like teak, but it's hard to say without some good close-up shots.  
The three screw plug covers on the back posts are odd, too--I've never seen even one of those at that location on a Danish piece.  at least not that I can recall.  
For what it's worth, American furniture is often not marked and Danish furniture usually is marked, if only with a "Made in Denmark" somewhere on it.  Again, just a guideline, not a hard and fast rule.

Tell City Chair Co. (based in Indiana, USA) made some chairs and sofas that were based on the Hvidt "ski slope" arms. However, I don't recall seeing one with the triple plug detail at the top of the slope.

I am based in Hampshire UK.  I need to sell this suite as I don't have the room for it.  Any idea what it might be worth?  I paid £400 to have the cushions made for it.
