Personally too soft for me, but it didn’t have a smell, it was convenient, and it is well made.

So, if you're considering this please reconsider. I ordered 1. Groupon charged me for 10. Thousands of dollars! They immediately recognized the mistake and canceled 5 of them. Only 5. They said i couldn't return the factory UNOPENED BOXES due to covid. After weeks of complaints they reluctantly sent me prepaid USPS postage labels for 4 which USPS REFUSED due to the weight. Lost $4400.

Just buy it! Absolutely the most comfortable bed I've slept on. Saved me spending over a grand on a mattress locally. I got the king and it's huge. Better yet, my wife likes as much as me. Yeah, shipping took an extra week or two, but I was fully expecting that after reading numerous reviews. I really can't say enough nice things about it.

Shipping was great. Took about a week to get it. Was very easy to set up. Once you cut the plastic,, it expands within minutes.. Love the quality.
