Hi Gena.

A recent article in The Guardian will make interesting reading for you Read here.

I don't really know what to say.

Personally, I would want to know what they mean by 'within tolerances'.

FIRA are the furniture industry's watchdogs and they are the ones who will have the actual data on 'sag ratio' of latex.

However, this will have relevance to the actual depth of latex used in your particular mattress - which at this point is an unknown.

Sealy use Innergetic latex (same as Silentnight, Rest Assured and the rest of the Silentnight family).

This is a product from Latexco [I believe it to be a blend of natural latex and synthetic latex] I am not privvy to the actual data sheet [FIRA will most definitely have this] It may be entirely synthetic [!] who knows?

I mention this because this may help in you getting some sort of recompense.

The description on your particular mattress clearly states " ..Incorporating a generous layer of Innergetic latex for outstanding comfort and pressure relief ..".

I am assuming that you were not told the actual depth of 'latex' used.

Even though this phrase appears on many Sealy mattress models that use Innergetic latex - the depth is never divulged [!].

As this was the reason for your complaint I would expect Tesco Direct / Sealy / FIRA tecnicians to proffer this information to you on request.

Secondly, if the depth of Innergetic latex used in this particular model was a paltry 1-2cm or so, then obviously it would not have the durability property to last - and so, the sagging would indeed be 'within tolerance' for the depth used [!].

The fact that you did not know the depth of 'latex' used / Tesco did not tell you / Sealy did not make this information available to you ..

gives you an argument that the phrase "a generous layer .." was misleading - but this rests on you knowing what the depth actually is.

The OED definition of 'generous' is "(of a thing) larger or more plentiful than is usual or necessary".

I would expect a layer of latex as the primary layer on a mattress to be a minimum of 3-4cm (5-6cm would be considered generous).

Sorry, I can't be of much help here.

Ryan and I constantly bang on about consumers asking these questions to ensure they know what they are buying by component weight, quality and depth.

Manufacturers and retailers should be forced through legislation to supply this information the same way as ingredients on food items are.
