The Leesa gets great ratings on the web, so I’m excited to give it a try!

I get a lot of questions on other mattresses right after opening – the big thing to know is that it’s going to take about 24 hours for the mattress to be really ready (though you can sleep on it immediately).  The big things that will change are the initial smell (called off-gassing) and the firmness.

Leesa First ImpressionsOff-gassing

Since the mattress comes compressed, there will be a slight smell immediately upon opening.  This happens for all mattresses that are shipped like this, and Leesa’s smell is actually less than others that I have tried.  The smell will be totally gone within 24 hours, sooner if you open a window and turn on a fan.  Occasionally someone will have a sensitive nose and I’ll hear complaints on this, so if that’s you – maybe give the mattress an extra day or two before you sleep on it.

Firmness

The mattress was just compressed completely, so even though it looks like it has decompressed completely just a few minutes after opening, the foam is going to continue to expand for up to a week.  The mattress will still feel great immediately, but it will continue to expand and provide more support a few days after opening.

To see how I liked the mattress after I slept on it for a week, check out my full Leesa mattress review.

  1. The smell is bad and it never goes away (it’s been weeks for mine). Some people just aren’t very sensitive, or have plugged sinuses, but even they will notice if they stick their noses up against the mattress.

    • Our stinks too. It’s been a few days with all windows open 24/7, and I can’t even sleep in the same room, let alone ON the mattress.
