I note that your body weights are just under 16st and just under 12st, which would normally be best suited with a medium feel mattress.
|Upto 8 Stone / 50kg||Soft
|8-16 Stone / 50-101kg||Medium
|16 Stone / 101kg Upwards||Firm
It used to be that if you had back issues you ought to opt for a firm mattress, however, the current advice from organisations such as the Institute of Chiropractors http://www.chiropractic-uk.co.uk/time-to-change-your-mattress-244-news.aspx contradicts that advice.
The fact that your wife prefers a firm mattress with a topper would indicate that she finds firm too firm and again would be more suited to a medium at the outset.
The question regarding the joining of two double sized mattresses is a little more difficult to answer.
It is not a standard product made by us or any bed manufacturer, however, we can make such a product but as it would be a bespoke size (8ft wide x 6ft 3in long)
It would not be covered by our 60 day love it or return it guarantee, and would have a cost implication.
I am not aware of anywhere that would make such a bespoke size one piece topper, you may need to purchase 2 double sized toppers and sew them together. Such a product would only be available in our Artisan range.
The issue of the bases is something that would cause further difficulty, as it would require the ability to join two normal double sizes together at points where no joining points are readily available. All our bases are divan bases and manufactured for us.
We do not sell anyone else’s products. If you wife suffers from allergies, then one of our Contemporary (Latex & Hybrid Foam) products may be more suitable, although these cannot be made to join together.
I hope that the above is of assistance to you, but if you have any further queries, please call our office on 0161 437 4419.
Kind Regards Gary
