These are outstanding. Turns any mattress into a dream.
Best we’ve found. We bought our first from Amazon, it’s ok. Then bought one of these from woot and loved it, and moved it to our primary bed. We upgraded from a queen to king. Waited but did not find this one again after waiting a bit so we bought one from Wayfair. It was terrible. Gave it away as soon as we had a chance to order its replacement from woot.
Seriously outstanding. Best sleep I’ve had in years.
