Yes, it fits my 22'' mattress and mine is only that size because I also have a feather topper under this Mattress topper

My guess would be "no". Our mattress is about 10" deep and the cover fits comfortably . . . it could stretch another couple inches, max. Any deeper than that and the cover wouldn't stay on it would keep popping off.

My mattress set up is 12" deep, the box sheet fit loosely. I would almost say for sure it would fit a 15" set but could not say if it would stretch to fit 18". Hope this helps.

My mattress is oval and it measures 18x14. It might be a little tight for your mattress. I hope that helps.

It will fit 15 inch I know.....I don't know about 18 inches. I have it across the foot of a king size bed. So, I think it would fit a deep mattress, mine is but, I only use one side to fit, the other side is cut and laid out flat. I hope this helps.

i have a split king mattress and these sheets fit perfectly. they measure 15 1/2 ' which is perfect for my bed. i don't think that they would fit an 18' mattress.

I don't know but my mattress is pretty deep and it fits fine. If you want me to measure mine, I will, just let me know

It will fit a 12" deep mattress. I believe that I experience a deeper sleep and THAT is what has helped my body heal and I am now experiencing less pain.

My mattress is 14", and it fits just right. I don't think it would fit well on a 18-20".

Yes, i have no doubt it would fit. My mattress is fitting perfectly and still there are few inches left so you have some flexibility. Good choice

I have a standard depth extra long mattress. It goes on really easily. There does appear to be room to fit a mattress with a greater depth though.

My mattress is 15", and this pad is way big for it. Measuring with a yardstick while it's on the bed, it will fit at least an 18" mattress.

I don't know as my son has it at school right now, but it didn't fit his mattress. I ordered a different sheet set that says it fits 19" deep mattresses. I think in my son's case the problem is the length of the mattress and not the depth. For some reason, his mattresses must be extra extra long. Even the sheets he had last year do not fit.

It is hard for to say if it will fit your 18 inch mattress because my mattress isn't that thick. What I can tell you is that when I stretch out the sheet it is about 22-24 inches long. I would think it would fit your mattress but it is a guess.

I don't know. I purchased it for a queen-sized mattress, and it fits adequately.

My mattress is 13" and there is quite a lot of room left but I think 18" might be too much to try to cover. I would guess 16" might be the limit.
