I tried "John Lewis & Partners Essentials Collection Pocket 1000, Ortho Support, Pocket Spring Turnable Mattress" at Johnlewis, reached home. ordered one of them online for my master bed. Post delivery i noticed the mattress quality is more firmer compared to the one i checked in the shop. I told to myself the one in showroom must have been used my many visitors, convinced myself & i made second order for the same mattresses for my another bed on the same day. The nightmare started on the first night i started using the mattresses, I couldn't enzoy after couple of hours, it start with light headache and then vomiting sensations. In the morning I look awkward and took paracetamols and headed to my work. Being stupid i thought the root cause could be with my pillows. so next night i changed pillows & there was no luck. same headache and voting sensations on the second night. third day morning slept almost whole day in my old mattress for many hours and again for the last time tried one more night with no change in experience. I vomited in the night on the 3rd day. Whilst writing this - its my fourth day i am still feeling sick & body pain. I am meeting my GP tomorrow. Today first thing then I called John lewis and cancelled my second mattresses order. Being a blind beleiver of john lewis quality and its customer service I called and shared the experience with their customer service to check my options on the first mattress for a return. you will not beleive the person on the phone after hearing the whole story asked to sleep in the same john lewis mattresses as i will get used to it and it becomes better day by day. There bluntly said is no other options they can provide. (JL can replay the recorded CS audio if they have any doubt) I really got upset and asked myself is it worth doing any businses with John lewis again? ever again? John lewis - you are not even ready to listen my experience, not even tried to understand the gaps with the product i am complaining about. There is no interest for your processes to close the product gaps that made me sick. You never tried to understand and give a better experience to the people you blindly trusted. Good bye John Lewis, I am one of the loyal john lewis customer like to end the blind trust i had with your company & products. May be you might get businesses but if you continue the same i don't think you as a company will survive.
