  • good but HOT

    If you do not get warm easily in your sleep this is a very nice high quality mattress protector/pad- however my boyfriend and I both are warmer natured and even if I sleep on it alone with the temperature at 68, I will end up sweating. Not sure if it is because of the waterproofing but I'm sad to say we are having to give this one away. Otherwise a very nice comfortable and padded protector.

    This is a really nice mattress pad. It is waterproof, but no eplastic is used. It is high loft and very soft. It definitely improves any mattress.

  • Good quality but sweatin' to the oldies

    Received this fine quality mattress pad and was very happy. My man and I have slept on this goodness for over a week now and have woken up every night in a pool of our own sweat. All attempts to rectify the situation by turning down the heat, wearing less to bed, etc have ended up in the same result. So, sadly, I think we have to kick this over to the guest bedroom and make our guests suffer. Perhaps too waterproof?

  • Sleep like a baby!!

    I started my search for a mattress pad and thought nothing but a feather down mattress pad would give the the comfort I was looking for....but given the reviews of many other EXTREMELY expensive mattress pads, I opted for the the Sleep Philisophy Harmony Mattress Pad and am SO HAPPY with my purchase. There is a noticeable difference in the comfort of my bed now -- light and fluffy...like sleeping on air. I have a King Sized Sleep Number Bed -- the pad fits snug and perfect! The only smell I noticed was when I initially took it out of the plastic bad (I blame the bag, not the mattress). That smell dissapated soon after removing it from the bag, so no worries there. I haven't washed it yet, but I expect it will wash fine as the material appear to be good quality. I highly recomend.

  • Great purchase!

    I was looking for a mattress pad that not only was waterproof, but also added a little extra cushion to my worn-in mattress. This pad does both & I love it. It even goes through the washer & dryer fantastically too! :) Definitely worth it!

Yes. I just bought a two inch foam mattress topper and have this cover on top. The pockets are deep. Fits great. Machine washable. lanamamma on Oct 10, 2013

This description says it has a pocket depth of 13", but also says it fits mattresses that are 18" deep. So, does it fit 18" or 13", or do I misunderstand different measurements that are really the same? crwb on May 21, 2013

Answer This Question

Hello crwb, The "Sleep Philosophy Harmony 3M Scotchguard Treated Waterproof Mattress Pad" will fit the 18" and 13" mattresses, with the obvious difference that the 13" would tuck under the mattress more.
