A foam or a coiled spring mattress? It really depends on your preferences. Foam mattresses offer a plusher feel, whereas spring mattresses provide a firmer foundation. Depending on your lifestyle, you may prefer either type of mattress. Spring mattresses are more expensive than foam ones, so they may be an option you consider if you like jumping on the bed. In general, however, spring mattresses are the better choice for those who like a firmer feel.
