Is pocket spring mattresses a good choice?

I found this pocket spring mattresses from an online store called “Oliverandsmith” . Price for this mattress is $264.99
Is this a better choice to use?

There’s no meaningful information provided about the quality (density) of the foams within that mattress. You can’t make an educated choice until you acquire information from the manufacturer about the density of the comfort materials being used. Start with that.
