I ordered the Alwyn home stijn mattress in a fulldouble with the thickness of 10”. First of all upon opening I noticed it did not have a chemical smell like other beds I have purchased in the past. I would say it took approximately 2 hours for us to see if all the way fluffed outexpanded. It is for my son’s bed and the thickness is perfect for his bed. He has yet to sleep on it but just lounging on to watch tv and us laying on it to just try it for a couple minutes it is comfortable. I would describe it to be a good in between as fair as firmness. It seems firm but not too firm and also not super soft that it’s hard to get up. Like I mentioned we haven’t slept on it a full night just yet but at first impression it seems to be of good quality. I will update once we have had it a few nights. We have family visiting soon that will be sleeping on it so we will also get feedback from them. I am happy with the fast delivery and compact size for transportation. So far I am impressed.
