Hi James.

It's unfortunate that apart from a detailed and lengthy listing of the spring composition of the above mattresses there is precious little detail on what the upholstery layers consist of.

Even a combined upholstery weight would have been useful in order to come to some conclusion as to why you like these particular models.

It may be worth you enquiring further as there are other retailers stocking Harrisons mattresses under varying names which may give you additional options for choice.

We tend to use Vi Spring as a means of comparison.

Along with Savoir Beds they are amongst the countries premium brand names in the industry.

Their faith in their products give rise to a complete and utter breakdown of all their component parts so you know exactly where your money is going.

With this in mind, I would suggest you also look at Vi Spring offerings and once you find a particular model you like we will be able to discuss it further and in detail.

John and Ryan.
