My daughters college does not loft their beds. We are looking at the risers but the highest we could find was eight inches
We were thinking of getting a thicker mattress topper. Has anyone bought a 10 or 12 topper?
Because of safety, does the school say they allow risers on the beds or give an idea of high they allow the risers to be?
Double check with the school if the beds have built in risers (or adjustable height). My kids’ school does.
Both of my kid’s undergrad schools had beds where the student could adjust the height. People came around during freshman move-in to help. My S used I think 7 inch or so bed risers in grad school and he never mentioned that he had any problem.
S never lofted his bed per se, but at the highest setting the bed sat at least 2. 5 ft off the floor. Plenty of room for storage boxes, etc.
My DD school did offer lofting (rental), but my DD chose to purchase cinder blocks (housing office sold them at move-in) to raise the bed enough to put plastic drawer underneath. We stacked 2 (the tall way). She goes to school in a part of the country were there aren’t earthquakes, so this type of lift was approved. Check with the school to see what they allow. As some people mentioned, some beds are adjustable, but not usually enough to put much storage underneath.
Regarding the mattress topper, we bought a 4 inch foam topper and it was plenty. Ordered on Amazon. Storing it during the summer was a challenge. 
Why do you think you need a 8-10’inch mattress topper? 2-4 inches should be fine.
Some schools do NOT allow lifting of beds in any way shape or form. No rack raisers, beds don’t loft.
Really the rack raisers you buy (the things that go under each leg of the bed) will only raise the bed high enough to maybe store suitcases or boxes underneath…not high enough for a couch.
Why do you think you must loft the bed?
10" isn’t a mattress topper. It’s a second mattress. Your child doesn’t need a 12-15" mattress. Get a 3,4-inch topper and a padded mattress cover - that should do it.
@SlackerMomMD Clearly you have not read the story of the Princess and the Pea!
I just was in Target and they sell a 6" ‘topper’ for $190. It is TXL, too, which is unusual to find - usually you have to just use a T size and it’s a couple inches too short on the TXL mattress, which is no problem.
@EarlVanDorn - I tried to work Princess and the Pea into my post but I couldn’t do it.
My daughters are definitely princesses aided by generous grandparents who got them the 8 inch mattress toppers! They also supply such luxuries as laundry service and Canada goose coats! Lucky girls!
Before you buy anything see what the school allows…my DD’s school had beds that you could adjust the height of and you were not allowed to use risers.
If you get a thick mattress topper, make sure the sheets will go over it. Trust me on this - I’m fairly sure my kid still cusses under her breath every time she washes her sheets.
@tutumom2001 - That would mean my DD would be cussing only once a year. HAHAHAHA! Gross, I know.
If left to his own devices, I’m not sure S16 would wash his that often.
My DD firmly believes that washing sheets ruins them. They can NEVER be as soft as when she has slept upon them for 5000 consecutive nights… >shudder<
I did buy both of my kids thickest topper I could find. I think few years back it was 5-6 in. Dorm mattresses were so thin, they had no problem using their sheets to cover both the mattress and the topper.
I have opposite problem with D2 when it comes to sheets. She likes them really soft and washed. She holds on to her sheets much longer than I would like.
We had ordered a pretty expensive mattress topper to pick up at BBB when DD was a college freshman. Much to our surprise, the dorm mattresses were brand spanking new…and very comfortable…and nice. So…we exchanged the thicker expensive topper for s thinner one…and also got a very nice mattress pad. Worked very well.
What I’m saying is…YMMV on the mattress quality.
Interesting…I never even considered a mattress topper and neither of my kids have ever complained about their comfort. Either they are not picky in this regard and/or their schools provide good comfortable mattresses. I’m pretty sure the former is true, don’t know about the latter.
