Purple's coil system doesn't compare to a traditional spring mattress. Spring mattresses are typically made using one piece of metal that connects each spring together, reducing responsiveness and increasing motion transfer.
If that doesn't sound like your jam, we suggest individually pocketed support coils. Coils are individually responsive so you get superior pressure relief and motion isolation. On top of that, they are as quiet as a mouse! No more squeaky springs. Get the best with the Purple coil system.
