30K to Build a sweet home - Master bedroom

I am using grey colour for my room, and I just did a very simple design, this is because of limitation of this room, the space too small, we unable to do the design I want, but after all, I found that maybe we can do, the design I want but just need to modify some idea, but is was too late I am so regret.. anywhere I have pretty good mattress : Serta New sophistication, my friends help me to get the reject set (miss alignment for the Belgium latex layer) for just SGD 500, original with promotion price was SGD 4800, after cover bed sheet, very difficult to see the faulty, and just cosmetic effect, function unchanged, I feel very comfortable for this mattress. and super value for money.
