For over a year, my husband and I have been trying to decide which mattress brand to purchase to replace our aging Sleep Number bed. He suffers from COPD, back issues and has been unable to sleep in our bed for a while. Considered purchasing a new mattress with an adjustable base, but were concerned this wouldn't solve our issues. After searching several online sites, I came across this topper, read the reviews and figured we had nothing to loose. WOW, this topper has totally transformed our bed! It cradles your body and since we put it over our Sleep Number mattress, we are able to somewhat adjust the firmness. We are both finally getting a great nights sleep and I wondered why I wasn't exhausted by late afternoon anymore...duh, I'm sleeping more soundly! Our animals also love it! Also loved that this product was made in the USA and not overseas with "unknown" materials. My only complaint would be that Wayfair dropped the price by $30 a few days after I purchased it.
