Here is my personal experience with nilkamal branded chairs. We heard it as a good company, asked suggestions from few known people and thought to go for it. We bought 2 nilkamal chairs for regular use at our residence. Each costed around 800rs.
Design was pretty good, but we came to know the drawbacks few days later. Though the seating position is comfortable, it lacks sturdyness. Back resting portion is very delicate. It moves backward if little pressure is applied and results in chair imbalance.My kid fell down for the same reason.
One more thing is that it scratches wall paint due to sharp backside finishing. We found many scratches over new wall and felt very bad.
I suggest you to look carefully into feature before you buy.
