I'm looking for a new mattress also. TY for posting the comments gave me some ideas to check out.

After spending four years sleeping on the floor (cement) in Korea, I find American's obsession with finding the perfect mattress rather amusing.

I bought one recently. I don't know the brand (sorry). But I love it. It's so comfortable. I've had the best sleep since I bought it. Sex is good on it too.

I bought a Nectar and LOVE LOVE LOVE it.

-- Full 365 DAY no-risk tryout (if you return it no questions asked, you get a full refund including shipping, taxes, everything).

-- LIFETIME full warranty.

-- It comes with two (expensive) pillows that are awesome as well.

If the label says Serta, run away. Quickly. They definitely don't make them like they used to. The single sided unflippable ones are crap.

I love a mattress that is firm. After coming back from holidays I bough one that was the firmest I could get and it is great.

I had memory foam and slept comfortably, but it was HOT and very hard to move around on. I now have a Purple, about a year now, Love it! A bit heavy, otherwise Perfect!

I love my memory foam mattress. I’ve herniated my L5-S1 disc twice so a comfortable bed is a priority of mine.

We bought a Serta hotel model. Double sided. I'd say get a double sided if you can find one. "Non fliffable lasts just as long" is the biggest lie ever.

I bought a $1,200 Tempur-Pedic and hated it it was too soft. I went to a mattress company in Oklahoma City that's been in business for 40 years and bought one of their innerspring mattresses for $400 including the box springs and my back loves it.

I bought a queen mattress for $250, after my divorce. It was the best I could afford, and it was/is total crap. However, I've got a three-inch memory foam topper, and a super thick mattress pad on top of it. Makes all the difference in the world.
It's more than ten years old now, and I don't expect I'll be replacing it anytime soon.

I can't recommend any particular mattress brand, but I'll swear by memory foam toppers and really thick mattress pads.

Hope you find something you will be happy with.

Rather fond of spring mattress with the a motor driven adjustable head and feet (the variable vibrating motors in different sections are also nice) That is my current system and I have just added a 3" memory foam (No textures) topper. Took a little getting used to but nice. Added a 1.5" memory foam (with textures) topper to a different bed and this was not a good choice.

I just got a Nectar and it is AWESOME!!! I have back issues from the military, and this is the first bed in years that has actually helped. I wake up now and feel good...at least for a few hours! lol

EDIT - researched a Casper, Nectar, and a Tuff and Needle. Price, warranty, shipping, and bed reviews got me on the Nectar.

Tempurpedic. I love my bed.

It isn't cheap, but I really like my Select Comfort bed.
