    What I wanted and needed
    I have been sleeping on my Sealy Cristal Advantage Firm queen size mattress since 23 December 2025. For the first eight nights it was just me, as my husband was away. I was worried that the comfort may change once there were two people sleeping on it. I have spent a lot of money previously on well known branded mattresses, only to have them start to dip on either side, turning into a banana. It has been 20 nights now, and so far so good. I admit I feel that Sealy is a reliable brand, so that persuaded my purchase. I rotated the mattress after two weeks, as that is the recommendation from Sealy. Apparently, this should continue for three months, rotating fortnightly, then after that time, rotate the mattress every three months. So I am absolutely following these guidelines. This mattress is extremely comfortable. As requested, it is very firm and that is what I wanted. I realise it's early days and truly hope this mattress continues to provide a restful night's sleep for many years.
