Whether it’s better to buy an expensive mattress depends on your needs, preferences, and budget. It’s often worth spending a little extra if you find a more durable model that better meets your needs. An improved sleep experience and a longer lifespan might ultimately make a more expensive mattress a better value than an affordably priced alternative. That said, a quality lower-priced mattress may be ideal if you’re not planning on using the mattress long term or you anticipate your needs may change.
