Simply Perfect Mattress

Hi there. Wondering your opinion on The Simply Perfect Mattress. Sold by The Foam Store. In Kitchener Ontario, Canada.
The specs are
Top layer 2in gel memory foam 4pcf
2nd layer 2 in foam, 2.5 pcf and 27 compression.
3rd support layer 6 in foam 2.5 pcf and 35 compression.
Do u think this all foam mattress will provide enough support for someone 235lbs?
Thankyou
