I was researching the internet for a quality reproduction Saarrinen table for a friend's new apartment and found Rover Concepts. I tend to be wary of "knock offs" as they often turn out to be poorly manufactured products. After looking at many options— and, of course, at Ikea's model—Rove Concepts, although its version of the tulip table was pricer, the company had good reviews and also seemed trustworthy. 

The risk of buying a large table "sight unseen" over the web was overcome by a desire for (by many accounts) a quality reproduction than closely resembled the original. My friend ordered the round 40" tulip table with a Carrera white marble top. I can say, without reservation, that the quality of this table is fantastic. The powder coating on the base is even, its shape is flawless, and the marble top is subtly veined and smooth. 

The service was amazing by Rove Concept's sales people, Elly and James. Elly and James facilitated the sale beautifully and really made purchasing a piece of furniture from an online company seamless. 
Can't say this enough: truly impeccable customer service by well-trained knowledgable people.  I would highly recommend Rove Concepts as a source for reproduction classic modern  furniture.
