Recently my wife bought him a "feather bed" which sits on top of the usual mattress and adds considerably to it's weight. This has caused some of the wooden members of the construction to break, and I set out to fashion a repair.
To my horror I found that these wooden parts which are about 200 cm x 3 cm x 2cm have been fabricated out of short lengths of rubber wood around 20 x 3 x 2 which have been joined together by being machined on the ends into a male and female tapered comb, and then glued to form a single piece of material which can be used as virgin timber.
To all intents and purposes all the glued joints have failed as the structure progressively deflected, about 50 of them, and a repair is more or less impossible.
Just something to watch out for when buying commercial furniture nowadays.
It's good to be able to buy a bed or a table built at Vietnamese wage rates but less good if it's prone to collapse without warning into a pile of sixty or seventy bits of flotsam if overloaded by a few kilos.
