Mattress will begin expanding in minutes after unpacking and will be usable within 1 day. Please allow the mattress to expand for at least 24 hours before you sleep on it. Mattress may take up to 30 days to fully restore. Due to compressed packaging, the mattress height may be less by around 3-4cm after expansion. Please do not place an order if you require an exact 24cm height. Different parts of the mattress can vary in height due to the mattress being a 9-zone model to provide different levels of support and also there may be manufacturing differences (e.g. the height of the edges can be lower as compared to the main areas of the mattress). Patterns on the surface may vary from batch to batch IMPORTANT: After opening the box, please place the mattress on a flat, even ground surface before unrolling and opening the vacuum packaging to commence the expansion process. Do not open the mattress for expansion on a bed frame.
