Selecting a mattress for back pain is highly personal, but research suggests that upgrading from an old, unsupportive bed to almost any quality new mattress often significantly improves pain and sleep quality. For chronic back pain, specialized models like the Saatva RX offer targeted lumbar zones, while value-focused hybrids like the Brooklyn Bedding Signature or Origin LumbarCloud provide excellent support for a lower investment. Always prioritize mattresses with generous trial periods, as individual comfort needs vary greatly and back pain relief often requires a testing period.
