"Clinical assessment of sleep profile"?

Hi LenF,

Steel innersprings in general are a durable component so an innerspring isn’t normally the weakest link in a mattress. The durability and useful life of a mattress will depend much more on the types and quality/durability of the materials or components that are on top of the innerspring than the innerspring itself.

There will be a break in and adjustment period for any new mattress or sleeping system as the mattress loses any of it’s “false firmness” and the cover stretches and loosens a little and the materials settle and your body gets used to a sleeping surface that is different from what it is used to (see post #3 here). This would typically be a few weeks but it can be shorter or longer depending on the specifics of the person and the mattress (higher density materials like latex can take longer) and it can be surprising to many people how much their sleeping experience can change over the course of the first month or so (and on some occasions even longer).

A good retailer should be willing to phone their factory rep to see if they can find out this information for their customers and not make their customers do their job for them. Many mainstream mattress manufacturers don’t disclose this information at all but there are also some others where the factory rep will disclose it to one of their retailers even though the company itself won’t disclose it directly to consumers.

If for any reason they are either unwilling or unable to provide you with the information you need to make an informed choice I would avoid the mattress completely.
