This is a step up from the 4" foam mattress, and the difference is night and day. This is a soft memory foam, mostly used for children. Though adults might also find it comfortable for a store away spare mattress.
If you have a young child or kids with a bunk bed/trundle, this mattress will be a good choice without breaking the bank and should last until they want to move up to a full-size mattress (they always want to).
