Powerd recliners have pretty robust mechanisms and will be covered by the standard manufacturers guarantee and if paying by credit card you are afforded further protection from sec 75 and some credit cards offer an extended warranty that may add an additional year to a product’s original warranty. Barclaycard comes to mind, as one such provider, that may still offer this.
My parents renewed their leather sofa’s last year with powered recliners and didn’t take out extra cover, as my dads previous powered recling chair lasted 25yrs with only the power supply transformer being replace at a cost of £25.
What can go wrong, well not alot really – loose connections or broken control wire (cheap easy repair), faulty transformer (As little as £25), faulty motor actuator (around £60) and most repairs are within the scope of a competent DIYer.
Frames come with a 5 or 10year guarantee, as part of the purchase price anyway, so you got to ask yourself the likelyhood of you staining or ripping the sofa, which will be covered by your home insurance anyway if you have accidental damage cover.
Foam cushions loosing the viscosity, will likely warrant the company sending an independant assessor out, who may side with the company and put it down to fair ware and tear, even though in reality it isn’t, its just in most cases they will favour the company, as they are the one paying and keeping them in regular work!
My last sofa, the foam sagged but was refused repair as the independant assessor told the company it was in tollerance even though it wasnt. I initiated a sec 75 claim but the credit card company said they wouldn’t help, as an independant assessor report said it was in tollerance and I would have to pay for my own assessor (£200ish at the time) before they would take a sec75 claim anyfurther. I decided to get an upholster out and pay for them to replace the foam in the 5 seat cushions with HD foam, rather than the MD foam the sofa’s came with and would have been replaced with if the company did repair. The upholster said he see’s it all the time! Anyhow, never had issue afterwards.
The other option is to look for your own independant furniture warranty, if you think you need it. I never bother TBH.
