Restonic beds

I bought a restonic bed in 2022 December last year from Ok Furniture.After slepping on the bed for Months i reallized the matress is losing its shape and is torn on the side of the matress.After phoning Restonic while the bed is still under qaurentee Restonic refuses to exhange the matress for new one.I paid over R10 000 for.the bed and expected quility guarenteed.Im very disapointed in Restonic and would never buy a Restonic bed again.Bad Quility beds.
