Sleeping on a cheap mattress can make financial sense at 25 and still look like a lousy bargain at 55. Age alone does not determine when a mattress deserves an upgrade. The real question involves what the mattress costs you over time, including its durability, comfort, and effect on your daily routine.
A low-priced mattress that supports comfortable sleep for years can beat an expensive model that disappoints after a few months. However, a sagging bed that leaves you shopping for replacements every few years can quietly drain your budget. The smartest buying decision considers the mattress’s entire lifespan, not just the price tag at checkout.
