Absolute disgusting behaviour from the company and the customer service team... 1 year old mattress is sagging and dipping more than it should... they have con my family out of money for this mattress that they are unwilling to give an exchange on... also has a 10 year guarantee... they have claimed our bed slats were not suitable for the mattress... it’s ridiculous... no where states or no one said to us when buying the mattress that the 10 GUARANTEE would be invalid if the slats were too far apart for “their” standards... if we had known we would have made precautions to protect the mattress... but yet it’s the top of the mattress that is dipping and sagging.. not the bottom.. it’s terrible service.. should not be happening to a 1 year old mattress... they will use any excuse not to exchange or to stick to their word... as I can see the other reviews.. I’m not the only customer who thinks so ..
