3K can allow u to consider kingkoil, slumberland, vono, starrynite, therapedic....etc...international brands.

3k for a local brand seems too much in my opinion.

Goodnite is actually a decent mattress brand although if not mistaken is from local Malaysia. Their bed is usually good and affordable too as compare to other top brand. Sleep matics is rather new and unheard of in the mattress world. although they claim to be USA, but i suspect it to be local Malaysia cap-ayam(not proven) brand sold at a high price just my two cents though, no prove
