i had a really hard mattress for years, was due for a new one. waking up in pain, back and neck, prior condition. went to local mattress store and was desperate for relief, originally purchased tempurpedic rhapsody breeze, i was on a 3 mo trial no fee return,started to have neck pain, also a prior condition. Went back to store to let them know and was shown this one for $1000.00 more. Salesperson said he had neck issues and he had this dormeo mattress himself and was really happy with it. Dormeo delivred all fine until about 3 mos in and then i started waking up with sharp pains in my lower back, could not get comfortable, started sleeping on floor occasionally . Over time the mattress has gotten softer and softer with no support, at least for me. its probably a well made mattress for some, but my experience has not been pleasant nor positive. total cost of this abomination is $4700. it's a car payment a month for me I have not been back to store to seek answers, my suspicion is they will say 1 return/exchange only, store policy. unless u want a really super soft bed, i do not reccomend dormeo. i would like to sell this at a reduced price and get another tempurpedic.
