Hi LindsayGenius,
The Morgongava, the Malfors, and the Moshult are all two sided.
There is more about the most important parts of the “value” of a mattress purchase in post #13 here but the most important part of “value” is how well a mattress (or a mattress/topper combination) matches your specific needs and preferences in terms of PPP (Posture and alignment, Pressure relief, and Personal preferences) so this would be my main consideration.
Other than this … if both are a good “match” for you in terms of PPP then a mattress/topper combination also has the advantages that I mentioned in my last reply.
The Morgongava is very similar to the previous Sultan Edsele and a forum search on Morgongava or on Edsele will bring up more comments and feedback about both of them.
