Bad service 
I bought a mattress from them on the 5th of Jan 2021 and it was delivered 8th Jan . Used it that same night , only to realise that the one side of the mattress is soft/sagging ,while the other side is firm as a new mattress should be .

I immediately complained about it and was promised that the supplier (cloud nine) will come and inspect .So the cloud nine guy comes a week later after I had to call and nag to find out the progress , then he takes measurements of the mattress (does not inspect the main  reason of the complaint ???)  .

Send measurements to management who send me an email to say there is nothing they found wrong with the mattress . 10 year services warranty falls aways and even the guarantee , for a mattress that is only a day old . Now they do not even respond to my email about the warranty and guarantee .

DO NOT BUY ANY Rest assured, Matrix or Strandmattress . Customers services only applies when you are buying , not when you are not happy with their service .
