buying bed better test first. everyone size and requirement differs.

I would recommend Seahorse brand.

So far I feel quite good, especially for asian people (seahorse is HK brand)

Price range is 2.5-3k depending on model or size. dont know what tech they use.

The most important feature to me is the bed is more to hard (like coconut husk) but at the same time very light weight. so when change bedsheet no need to break back.

check their shop in 1U or sunway pyramid
