Any odour you detect when your mattress is first delivered is generally a short term issue and should not last any longer than two weeks. If you continue to have concerns regarding the odour, we recommend you sprinkle bicarbonate of soda on the mattress, leave for as long as possible, then give a light vacuum off. Alternatively placing the bicarbonate of soda in a bowl in the bedroom or spraying the mattress with a fabric deodorizer may also assist. Always check the suitability of spray prior to use.
