Opinions on Sealy Posturepedic Plus Hybrid High Point 14" Plush Mattress?

Hi everyone.

My fiance and I are looking for a new mattress. We went into Mattress Firm and fell in love with the Sealy Posturepedic Plus Hybrid High Point 14" Plush Mattress. However, the price tag is a little steep and we can't seem to find much about it outside reviews on their website.

We currently sleep on a rented inner spring mattress so we're pretty sure anything will be better than that. But we're also not super keen on spending over $2,000 on something we won't love.

We're looking at a queen size. He's 5'10 and I'm 5'1, both mid-size. We're side sleepers and both have pretty bad back pain from our bed.

We would also appreciate any insight in general about good mattresses for side sleepers, if you have any!

Thanks in advance for any help!
