In the cited tests, neither foam nor spring was objectively better. Foam can provide pressure relief and motion isolation, while coils allow airflow and sleep cooler than all-foam beds; some find that gel-infused foams sleep cooler and others detect little difference. Foam performance depends on comfort-layer materials and quality, so compare each mattress rather than relying on type alone.
Coil-based mattresses tend to sleep cooler than all-foam mattresses, while gel-infused foam feels cooler to some sleepers but not others.
Memory foam cooling
Some sleepers find that gel-infused foams sleep cooler, while others detect little difference. Talalay Global’s FAQ describes memory foam as trapping heat and causing a slow-responding sinking sensation.
If considering gel, check whether the mattress uses gel-infused foam.
Do not assume gel feels cooler to every sleeper.
Treat the heat comparison as a manufacturer claim.
Coil airflow
Coils leave room for airflow, so coil-based mattresses tend to sleep cooler than all-foam mattresses.
Look for space between coils when comparing airflow.
Compare a coil build with an all-foam option.
Latex foam
In CHOICE’s test, two latex mattresses felt cooler but still collected a lot of sweat.
Compare latex with the tested polyurethane foam models, not every foam mattress.
Remember that cooler feel does not mean sweat-free.
Body weight and sleep position may shape different wear patterns: heavier sleepers may wear a bed faster, while position may affect where indentations form.
Sleep position
Sleep position may influence where mattress indentations eventually form.
Note your usual sleep position when checking for wear.
Look for where indentations have formed.
Body weight
Higher body weight may wear a mattress more quickly, especially if it has soft foam layers.
Heavier sleepers may wear out a bed more quickly, especially if it contains soft foam layers; durability also depends on material quality and overall construction.
Soft foam
A bed with soft foam layers may wear out more quickly for heavier sleepers, so check material quality and overall construction.
Review the comfort-layer and support-core materials.
Consider material quality and overall construction when assessing durability.
The quoted comparison lists bounce ratings of low, medium to high, high, and low; it does not identify which material each rating belongs to.
Memory foam bounce
The quoted comparison lists bounce ratings, but this excerpt does not identify which materials they describe or how they feel during movement.
Compare the bounce of specific mattresses if you want a springier surface.
Check the mattress’s bounce comparison, not only its material name.
Polyfoam and latex bounce
Talalay Global describes Talalay as highly resilient and responsive; the quoted comparison excerpt does not identify which bounce ratings belong to polyfoam or latex.
Compare the bounce ratings if springiness matters.
Treat the description of Talalay as a manufacturer claim.
Latex mattresses may use different kinds of latex in the support core and comfort system, so check the material in each part.
Dunlop latex
Spindle says to ask for the ILD of each latex layer rather than treating the whole mattress as having one rating.
Ask which latex types appear in the support core.
Ask which latex types appear in the comfort system.
Request the ILD for each layer.
Talalay label
The mattress-type source describes latex generally, not Talalay-specific performance, so verify the actual construction rather than inferring it from a label.
Check which latex type is used in the support core.
Check which latex type is used in the comfort system.
Use independent test results and in-person visits to compare a mattress, then read the trial, return, and warranty terms before buying.
Independent tests
Which? says its mattress reviews use its own independent tests, while CHOICE found equal proportions of foam and spring mattresses with good, average, and poor performance in its tests.
Compare the reported performance results.
Check whether a review is based on independent tests.
Store test
Casper says shoppers can try products in person and chat with a Sleep Specialist at a store.
Try the product in person before buying.
Use the visit to talk with a Sleep Specialist.
Home sleep trial
Casper’s trial starts on delivery, lasts 100 nights, and requires the first 30 nights as an adjustment period.
Start the trial count on the delivery date.
Allow the required 30-night adjustment period before returning.
Check the trial’s end date and terms before purchase.
Return terms
Brentwood Home requires returned mattresses to be suitable for donation with the law tag attached, and says returns before its 30-day minimum trial carry a 15% restocking fee.
Check condition rules for stains, tears, odors, and soiling.
Confirm whether the law tag must stay attached.
The FTC says a warranty will not necessarily cover every situation or repair, so read the written warranty terms.
Before an early return, check the minimum period and fee.

How does latex compare with foam and coils for durability?
Sleep Foundation describes Dunlop latex as more durable than Talalay latex and virtually all polyfoams, but its cited durability note does not compare latex with coil mattresses.
The mattress-type source says latex builds may use different latex types in the support core and comfort system, but it does not compare Dunlop and Talalay processing. Check product specifications for the latex type used in each part.
