Where can I buy pieces of foam rubber?

I have a bed topper and just need to buy a couple of pieces of foam rubber for pressure points. Where would you suggest? Thanks in advance, Rick G

Try some of the upholstery places.

Try on Mahidol road on the left hand side as you go towards the airport. There is a shop sells a variety of foams. It is about 2/3rds down the road
