We bought two twins a couple weeks ago (firm for husband and medium for me) for our king size platform. I really couldn't be happier, and my husband likes his, too. We both slept better immediately. Less tossing and turning from him, and I wake up in the same position I fall asleep in, with no extra stiffness/soreness. My only complaint is that when we measured (twice!), the twin x 2 was the correct size according to the chart, but now that they are here, unwrapped, and inflated, maybe the twin XLs would have fit a little better length-wise? Not a big deal for us, though...the foot of the bed is covered in sheets/blankets anyway, so it's not worth time or effort to exchange over a couple inches...but this is just a heads up for others who have different taste in firmness levels and want to try doing the same. Wait for the occasional $50 off and splurge. I think these mattresses are definitely worth it!

It says medium firmness on the box. I would have just as soon slept on bricks.

Not as firm as I was expecting. I ordered the firm but the mattress is more like a medium firmness.

Comfortable. This was just right for a good night's rest. We love our new mattress.

Great mattress for a great price

Bring a buddy to lift with you as it is heavy. But install is very easy.

Big man needs support and coolness. I got both. Great purchase for me.

Had high hope based on prior reviews. Purchased the first of Sept and so far for 2 1/2 weeks it has exceeded my expectations.

No obnoxious odors when first inflated. Heavy so it doesn’t slide around. Comfy. A little too soft for my taste.

Very firm but great
