Index seems to have low quality and overpriced furniture. Anything furniture I've bought there 20,00-45,000 baht couches and chairs come apart and the upholstery rips easy.
IKEA seems a tad cheaper and more modern. Again, quality is always suspect. Good return policy. Good meatballs.
If you are looking for high end furniture you'll need to go to Bangkok and have it shipped to your home.
