Hey Newdgo.
Welcome to our Mattress Forum 
and congrats on the big move to Vancouver! It’s a huge transition, and finding the right mattress for your new home is definitely an important part of getting settled.
It sounds like you’ve had a great experience with your Selther Ortoflex G5, and I can understand how hard it is to find something that matches up after so many years. You’re on the right track with seeking out a medium-firm hybrid that’s friendly to side sleeping and fits your budget.
Are you seeking a twin? Queen?
A quick note about online reviews - we usually caution people not to rely too heavily on them. Mattress comfort is super subjective and depends on a lot of factors: your weight, body type, sleeping position, and personal preferences. What works for one person might feel totally different to someone else, even on the exact same model.
Instead, we recommend using our Mattress Durability Guidelines to help evaluate a mattress’ materials and how long it will likely last. We also suggest checking out brands we’ve vetted on our Trusted Members as these companies are transparent about their materials and construction and offer great customer service, and a number include shipping options across Canada.
Also, feel free to reply here if you’d like help comparing specific models or materials we’re happy to walk you through it!
