I went to a Serta Showroom in Jurong Point yesterday. The sales person told me there was a promotion for all models of mattresses. Eg: Serta Diamond Suite was originally sold at $5k+ now going for just $2699. Is it true? Is this model really so expensive normally? Or is Serta just trying a marketting gimmick stating a way ex original price when normally the prices are just $2k+?

Bro, it is the norma that mattress are marked up about 50% their selling price then they mentioned they have 50% discount. You will see this when you visit Robinsons, Courts, Harvey Norman and other places or brands that sell mattresses.

Mattress is a very personal thing and you have to lie down as long as you pefer to have a better feel what you want.

You also need to balance your budget and the features of the series/model you intend to purchase.
