Common questions
Pod 4 or Pod Cover Pro — which should I buy?
Both are covers for your existing mattress. Pod Cover Pro if price decides (about $2,200 vs from $2,449); Pod 4 if you find it at a similar price or want the optional Eight Sleep mattress bundle.
Is the climate hardware actually identical?
Yes — same dual-zone water cooling/heating, same chiller, same temperature range. Both sit on your own mattress, so fit depends on that mattress, not on the cover.
Do both require the subscription?

Yes — both are cover layers that move to another standard mattress (Pod 4: 10–16 in thick, per Tom's Guide).
