Hi Laila,

The comfy night mattress that I've found is memory foam and cage sprung mattress.

There are no details on the density of the foam or depth which makes comparisons really difficult.

The cage sprung mattress is the worst construction method of all sprung mattresses I'm afraid so I wouldn't have a direct comparison as all my mattresses utilise high quality pocket springs.

You can see our video on what an open coil/ cage sprung / bonnell sprung system looks like here.

If you wanted something along those lines but a much higher quality please have a look at our Hybrid 6 which is a deep pocket sprung based hybrid foam mattress with matching topper.

For your weight this will give you a softer top layer with a medium overall support.

I wouldn't recommend a firm support or orthopedic mattress for your weight at this will be punishingly firm, especially if you have a previous injury.

The prices for each size are on the listing Laila.

If you require any further assistance please give our office a call on 0161 437 4419

Thanks - Lee
