One way that bed manufacturers have reduced the production costs of their beds is to stop making bases with springs in them (known as 'box spring' bases) and to replace them with what is basically just a plywood box. Here in Thailand virtually all mattress manufacturers make them this way and have tried to sell this to customers as some sort of benefit, saying that they have stopped 'motion transfer'. This is complete nonsense as box spring bases act as a form of shock absorber for the mattress and this foundation substantially increases how long the mattress will last.
The only 'benefit' is to the mattress manufacturer, who reduces his costs.
Here at Hugs Mattress Thailand we have now found a manufacturer of proper box spring bed bases here in Thailand and can supply them to customers throughout the Kingdom. We will shortly add them to our website but of course you can contact us for details by email or phone anytime.
