Discovered we needed a firmer mattress so we purchased the swirl hybrid. At first it was amazing. We stopped waking up stiff and sore and actually feeling better and more rested. However, its been about 6 weeks now and we are beginning to wonder if the bed is becoming too soft. The jury is still out at the moment but hoping things will improve.

Too hard tried returning after one day still waiting

Very pleased with the bed, comfy and responds well when moving, maybe firm for some.

Outstanding purchase. Very comfortable bed to sleep in.

Awesome mattress! We were worried about buying a cheaper mattress, but it has been excellent!

Great mattress, firmer than I thought but it works, very comfortable if you have lower back issues.

My son didn’t like it he said it was too hard!!!

It's been So long since I could lay down in comfort and usually I can't help but say "nice"! My new mattress is cool to sleep on, it was Very easy to set up. And I feel like the Best thing I've purchased in Years! I'll totally happy with my Zinus, I asked AI Grok, and it was Right!!

Easily the LEAST COMFORTABLE MATTRESS I have ever slept on in my 45 years. This thing is a BRICK. I honestly have to give it to them that this is the firmest 'bed in a box' that I would think possible. Althouth this bed is advertised as medium firm, it is beyond firm and was very painful to sleep on. There is ZERO give in the mattress so prepare to be being in an odd shape. This is especially hard if you are a side sleeper as your hips and shoulders to NOT sink into the bed at all, leading to some pretty bad back pain.

Measures 72 inches which is 3 inches shooof standard length. My custom built twin frame now has an overhang which is disappointing. I give it one star for simply misleading customers thats its a standard twin, i can understand it being short but the fact should be clearly stated in specifications and instead it says 75.
