The main difference
A foam mattress uses foam layers to create comfort and support. A spring mattress uses metal springs or pocket springs as its main support system, often with comfort layers above.
Neither type is automatically better for everyone. The right choice depends on how you like a mattress to feel, how much support you need and what you expect from the product.
Foam mattress feel
Foam mattresses often feel more even across the surface. Depending on the construction, they can reduce pressure around the shoulders, hips and back by distributing weight across the foam layers.
Memory foam responds more slowly and can create a closer, more cushioning feel. Reflex and support foams respond faster and help provide stability.
Spring mattress feel
Spring mattresses can feel more responsive and bouncy. Pocket spring designs can give more independent support than open coil designs, while traditional spring systems often feel more lively than foam.
Some customers prefer this bounce. Others prefer the steadier feel of foam.
Movement and partner disturbance
Foam can help reduce movement transfer because it absorbs motion rather than passing it across the whole mattress surface. This can be helpful if one person moves more during the night.
Spring mattresses vary. Pocket springs can reduce movement more effectively than some older spring designs, but the feel will depend on the full construction.
Which should you choose?
Choose foam if you want a steady surface, layered comfort and a mattress that can offer pressure relief without a spring feel. Choose springs if you prefer a more traditional, responsive mattress with bounce.
