Which mattress is good for back pain, spring or foam?

For back pain, foam mattress, especially memory foam or latex foam, is generally better than traditional spring mattress because foam provides better pressure relief, spinal alignment, and contouring support for back, similar to supportive cushioning protecting delicate items. Foam mattresses, particularly medium-firm memory foam, contour to body shape, supporting natural curve of spine, distributing weight evenly, and reducing pressure points on shoulders and hips, which helps alleviate back pain for many people, especially side and back sleepers. Spring mattresses, especially older innerspring with connected coils, may not provide enough contouring and can create pressure points, leading to misalignment and back pain, though modern pocketed coil hybrid with foam layers can be good for back pain too. Studies suggest medium-firm foam mattress is best for back pain, balancing support and comfort, keeping spine neutral. Latex foam also good for back pain due to supportive bounce. So for back pain, foam mattress, particularly memory foam or hybrid with foam top and pocketed coils, is generally better than pure spring mattress, as foam provides pressure relief and spinal alignment, reducing back pain, while spring alone may be too firm or not contouring enough.
