So far it seems like a decent mattress. It seems these days all the mattresses are “hybrid” (spring coil foam) and that is not what I wanted. I wanted a true memory foam. I originally was looking for a “firm” mattress but apparently they are hard to come by. So I went with the medium firm instead. I will update once I have had a chance to actually sleep on it. Photo is of mattress right after opening. I need to let it due it’s process for 24 hours (fully expand). But overall right now I’m happy with it.. Melissa. Cullman, AL. Thu Aug 27 2026

This mattress is SO thick and comfortable and was an amazing upgrade from our 8 year old mattress. It came in a small compact box and once opened the mattress rose to full size. This is seriously the perfect balance of memory foam yet support that allowed me to sleep throughout the night. It also has a cooling material to prevent being too warm at night. Cannot say enough good things about the quality and comfort!. Halee. Findlay, OH. Mon Aug 31 2026

This firm mattress offers reliable support with a simple, streamlined design that works well for a variety of sleepers. Built with layers of memory foam, it contours to your body to relieve pressure points while maintaining a stable, supportive feel. It is ideal for bunk beds, trundle setups, or compact spaces. We love that it arrives compressed in a box for easy delivery and expands quickly for immediate use.

I bought two of these for a pop-up trundle bed for guest use since it claimed to join into a king size bed. That is a different story. These mattress came vacuum-sealed and expanded to almost full size by the time I got the plastic off. The topper is nice material and can be zipped off for easy cleaning. I gave the mattresses about two days to fully expand and was surprised at how firm they are. Most "firm" mattresses are not very firm; however, I weigh just under 200lbs and I sunk in about a half-inch. It is a soft kind of firm, not a hard, cheap couch kind of firm. My wife laid on the top one and she was equally, pleasantly surprised. That says a lot, coming from her, as she has a bad hip and is very particular when it comes to mattresses. I do not believe you will find a better mattress in this price range and I would even venture that these out-match ones that are much more expensive. Very please with this purchase.. Chris. MI.
