I am 5'6 and 150 lbs my husband is 5'11 and 250 and we both are sore every day we sleep on this mattress.
The store did not offer every configuration and I was left to choose between soft med firm and med med firm ( all Dunlop) so the problem is that lying on the med does not immediately feel uncomfortable. It feels pleasantly supportive. Spend a night on it and it is a whole different ball game. Makes it impossible to trial in a show room. The other problem is the are taking their time shipping us replacement layers. I doubt that exchanging one layer will help all that much.
This was an expensive mistake.
Not recommended unless you live in the city these beds are made in and can try every configuration.

This mattress has helped so much with the pain I would get in my hip and back from sleeping on my innerspring mattress with a memory foam topper. Unlike the memory foam, latex does not sleep hot. I really don't remember if the latex mattress I bought is considered Serenity or Tranquility. I was fortunate to have a Savvy Rest store nearby so I could try out both the Talalay and Dunlop layers in different degrees of firmness. It is great that you have up to 90 days to exchange layers, as you really can't tell in the store how soft or firm the mattress feels until you sleep on it for several nights. I switched layers two times (easier to do if you buy a split layer rather than a solid piece). Also bought the adjustable bed. I can't wait to go to bed at night, and it's hard to get out of bed in the morning, as it's just so comfortable.

Purchased a Savvy Rest exactly one year ago and, for the past year, I have not had one single night's restful sleep--despite trying several costly "fixes" that the dealer recommended.

The first week I was in excruciating pain while I slept. The dealer said it was just that I had to get used to the mattress. After SIX MONTHS of being in pain, I finally started looking at fixes. (Savvy UNrest is one of the few latex manufacturers who don't offer an exchange or return policy. NOW I know why: their beds are awful and the would be out of business if the had an exchange policy.)

Worse, after only seven months, the side of the bed on which I slept started to sag. Badly. (I'm not a heavy person; I'm 5'6 and weigh 120.) The not-so-savvy SavvyRest dealer in suburban Chicago said that was normal, and all I had to do was flip the latex top layer. He acknowledged that by flipping the top layer, the feel would be much different--likely firmer. (Firmer like cement is more like it!)

So, I just switched to the other side of the bed. Sure enough, give months later, THAT side of the bed now sags.

Additionally, the cover is horribly uncomfortable (It's VERY stiff and thick), and defeats the purpose of sleeping on a latex mattress, which should "cradle" you.

The non-existent exchange policy left me stuck with this mattress so, as I said, I tried every (very expensive) fix the dealer recommended. Now, a year later, I am stuck buying another mattress--this time from a latex company that offers a sleep guarantee.

I wouldn't have a Savvy UNrest GIVEN to me for free!
