Hi Sion,

There definitely is the difference between a slatted base and a say sprung divan base. A slatted base will make a mattress firmer than say a sprung edged divan base, this is because the mattress is doing all of the work. The base is firm and so there's no give in it. We always recommend you try a mattress on both slatted and a sprung edge if you want to feel the subtle difference. Even sprung slats will be firmer than a sprung edge divan and you also get the issue of the 'humpback bridge' effect in some cases.

You are wise to board over the slats to stop dips and sinks in your mattress but it won't soften the mattress. I would recommend that if you're still having issues you give Bensons beds a call as it sounds like you may have too firm a mattress.

Even though the decadence mattress is listed as a medium tension mattress, it depends on your weight and preference. A medium tension for some can be a firm feeling mattress to others!

If you can provide us with more specifics such as height and weight we may be able to help further over the phone.

Please call the office on 0161 437 4419.

Kind Regards Gary
