Disappointed in St Dormier mattress cover

Hi dn,

Nice catch :)

I guess that solves the mystery of the amount of wool they use.

After considering on using an old mattress protector we had ~2 years old with our new SleepEZ 10,000, my wife and I have decided to upgrade the mattress protector as well. After researching a bunch of different protectors we decided on the St Dormier mattress cover for the wool and cotton combination to help us get the most out of our latex bed.

I am hoping we find this fits our PPP for our new mattress.

Thanks all for your comments regarding the St Dormier.

I have a new memory foam mattress that sleeps very hot in comparison to my old inner spring mattress and I'm trying a St Dormier pad to see if it helps regulate temperature. I'm a small side sleeper so have a soft mattress & soft topper but still find it a little hard on the shoulders. Like the OP I was surprised to see how thin this pad is when it arrived. However I love the feel of it and I think it does provide a thermal layer that helps to wick heat away during the night. I also love how I can still feel the softness of the mattress under it but somehow it has taken away the slight rubbery feel of the foam. I guess the body loves natural products. Because it's so light and stretchy though it doesn't introduce any tautness at all but just a little more cozy softness. The tips that Phoenix gave for side sleepers (pillow behind back and one under free arm) sound great.....will try tonight!

Hi Demeter,

Welcome to the Mattress Forum! :)!

Congrats on the St Dormier pad!

Yes, generally the issue of the sleeping microclimate on a mattress is a complex one. Heat and the inability to reposition, both tend to be characteristics of memory foam, especially when compared to previously sleeping on an innerspring mattress. Generally, Innerspring mattresses, do a good job of sleeping cool since they have less foam to trap heat in the mattress, but even so, some innerspring mattresses still end up sleeping hot depending on the very top layer of foam.

I am glad that you are enjoying new pad mattress combo and that it is just right, for you to still feel the softness of the mattress, You are correct that layers that are closer to the top sleeping surface will have the greatest impact upon comfort and sleeping temperature (including your mattress pad, sheets, and linen). There is more about the many variables that can affect the sleeping temperature of a mattress or sleeping system in post #2 here .

Thank you for mentioning the pillow sleep tips for side sleepers for any other consumer members that are reading your post. Pillows are a very personal choice and different people will have very different pillow preferences or different opinions about what they perceive as firm and soft or the general type of pillow that "feels" good to them but some of the information in the pillow thread here and the posts it links to can help you choose a pillow that is the best "match" for you and the mattress you are sleeping on.

Thank you again, and let us know how it works out in the long term!

I, too, am disappointed in the St. Dormier mattress protector. I bought it based on the many reviews on this site stating how thin it is and how it would not interfere with the feel of the mattress. I wanted something made of natural fibres and was o.k. with water resistance rather than waterproofing, so it seemed like a logical choice.

The protector is well made and flexible/stretchy. Beanbag notes that it doesn't contain much wool; I can't comment on that, but the entire protector (wool/cotton combined) is VERY puffy -- I measured mine and it is more than 1/2” thick. That's not what I would consider thin by any stretch of the imagination! My membrane protector, by comparison, is only 1/8" thick, including the cotton terry top.

My mattress, thankfully, is wonderful as is, but, adding this protector significantly affected the feel. The additional padding transformed my plush mattress to a much firmer surface, so much so, that I could no longer lay comfortably on my side without feeling pressure. I would consider it a mattress PAD rather than a protector.

Additionally, this expensive protector cannot be returned -- something I neglected to check before ordering online. I've now learned my lesson on that front!

I'll be continuing to look for something thinner and made of natural fibers; perhaps a wool puddle pad? All the ones I've seen online are 1/4" thick and supposedly soft so perhaps would not add that extra bit of firmness that alters the surface feel. I'd be interested to hear from anyone who has used one regarding that.
