Impressions permanent in less than two weeks

The mattress already has divots or impressions from where we sleep in less than two weeks. We are not overweight.

Perfect!

I was looking for more support something not too hard and not too soft and I settled for the plush and it’s perfect!

Firm and comfortable

The mattress is very firm, which I at first was unhappy about. However now, after several months, I am very glad I chose it.

So far so good

Have had one night only so far and we are very pleased. Slept very well! Just the right level of firmness for us.

Doesn’t feel like it did in the store

Hoping it will soften soon
