I’ve owned both the Casper and Novaform memory foam mattresses. Loved them both. Went with 3 Casper’s for my new house and am very pleased with the comfort and sleep quality I’m getting

All of those mattresses are memory foam type mattresses. That's oil based and bad for the environment. Also hot AF in the summer. I work in the bed trade. For decent value natural filled mattresses, Highgrove are great. If you have a high budget, try out Harrison Spinks, which are vastly more comfortable, 100% natural and chemical free, plus 100% recyclable.

The downside of this is that the returns rate for Simba/Casper/Emma is horrendously high. All that foam, where does it go? Those mattresses aren't resold.

Casper foam mattress with their “cooling tech” stuff. Got it from Costco and thought I’d hate it. Best fucking mattress I’ve ever had.  It’s freezing. I love it.

Love my foam mattress- Endy, Casper- there are lots. I got a great frame from Costco that was reasonably priced. New so no bed bugs

I am a fan of the Casper one they sell, it solved my lower back pain very quickly.

It’s all foam and I haven’t had it for very long yet so we’ll see about longevity. It’s not a very firm mattress for me but I’m pretty big at 225lbs. It has a zone comfort where it’s supposed to be firmer around the top and bottom of the bed and lighter around the center so your hips and backside don’t get contorted as you sleep. This is the only bed I’ve found comfortable enough to sleep on my back.

That is the one I have. It’s still been good to me since I bought it.

Thanks! I'm in early stages of choosing a twin mattress. I'm thinking of latex or memory foam. I'm a 140 pound woman. I've only seen slats for foundations. Are they really sufficient support? I have a Casper twin on a metal zinus frame now and I'm looking to get rid of both. Not enough support for me.

I’m a side and stomach sleeper and my partner is a back and side sleeper. We both love our firm Casper mattress.

Came in here to say literally the exact same thing. Add to this that in a big guy - 250lbs. Zero deflection as well.

Get a solid wood or steel platform frame and spend your money on a good midrange mattress (Costco, Sleep On Latex, Purple, Casper, Tuft & Needle) and a latex mattress topper if needed. I would estimate $200 frame, $500-$1000 mattress, $150 topper.
