Question: Will the fitted sheet stay tight on a 6 inch mattress?
Document: These were a disappointment, because if your looking for a cool crisp sheet to scroll into bed with, dont buy these, the bottom  sheet wont even stay on my mattress..nothing more aggravating then to get up in the morning and the whole sheet has come off the bed.
Previous reviews remarked on thinness of sheets so I was prepared for that & didn't mind that aspect. I get warm so I prefer cooler, lighter linens. However, I was not prepared for the sheets to have ground in stains. Washing did not remove them. Secondly, when putting on bottom fitted sheet, the elastic broke so it did not fit mattress snugly.I would not recommend these sheets. The adage &#34;you get what you paid for&#34; definitely applies.
For the price, these sheets are worth the money. The fitted bottom sheet does not fit as snugly as I would like, while the top sheet is not quite wide enough. The material, however, feels nice.
Finally, sheets that are smooth, soft and wrinkle free! The deep pockets fit beautifully over my mattress with featherbed. So much money wasted on coarse fabric sheet sets that ended up in the give away bag. Thank you AMAZON for the unbeatable price.
I love them! Can't beat the price. Super soft. Washed nicely. I have a very thick mattress and they still fit..can't wait to sleep on them tonight  ! Joyce Wilson lundberg
I have a firm memory foam mattress and this sheets fit perfectly,they are pure soft cotton and caress your body  all night long.I love them. I saw a realistic review and immediately ordered 3 sets.I wouldn't hesitate to re-order again.
The sheet is very thin
They went with the curtains i found for my room. The sheet set is wonderful.they are also really comforterble. Thank you.
This sheet set was just what i was looking for. Soft and pretty. The corners are deep pockets and fit my bed perfectly. Will purchase again for sure.
I was very disappointed when I rec'd this set. The queen set was very very light weight & so flimsy. They were described as deep pockets, but only 2 sides fit over my entire mattress side. Also, the color here on site is a more blue grey, but when they arrived they were a bright light blue, very light blue-not what is pictured. They look cheap, but were soft. I guess you get what you pay for...lesson learned!
Answer: The sheet is tight when they are washed, dried and put on the mattress but after sleeping on them, they stretch and fit loose. Otherwise they are well worth the price. I like them I just have to remove the sheets from the fitted corner space and remake the bed each morning in order to keep them tight for the next night.
