Will an extra long mattress fit on the top (not trundle) so long as it is regular thickness? i.e., 78"?

Extra long will probably be too long. I use a bunkbed mattress so it's not as high

We used a standard twin mattress and it fit perfectly. I don't know the dimensions of an extra long twin mattress, but my guess would be that it will not fit.

I put a six inch mattress and it fits great with some room left to spare. I would not go bigger than 8 inches and that may be a forced fit to slide it under the main bed.

Not sure if you could make it work. I bought extra long twin mattresses - fits perfectly

Yes...my mattress is more than 8" thick and although I personally don't tuck it in, yes...it would be able ro be tucked in.

No, it will be way to high. It comes with bent wood slats sit on the metal edges and flatten when you add the mattress. A box spring would add at least 6-10 inches and the mattress would be higher than the sides.

We have a Pillow Top mattress that is about 9 to 10 inches deep. There was plenty of room/material left when we put this on our bed. So I would say" Yes." However, If I were you, I would contact the Company (Linen Spa) who is selling the item and ask them "in the event this does not fit, can You return it?" They are very nice to work with and I'm sure they will answer your question(s). Hope this helps.

Yes. It is long enough. However, you will have to measure the clearance under your bed to determine how thick your mattress can be. The trundle adds only 2 inches, so you can put a reasonably thick mattress in it.

Our mattress is about 18 inches thick... 6 inches would be too thin and would not provide enough support, I don't think.

Yes...in fact, it is supposed to fit mattresses up to 22" thick - mine is only 10", & there is certainly a lot of its excess material tucked under my mattress! :)

I don't know exactly but I have a 11" heavy mattress on top and a 8" mattress on the trundle. I have no problems. Hope that helps.

I used a Lucid 10" memory foam Twin XL on the top and a Lucid 8" memory foam regular Twin on the trundle. It fits just right. Probably anything thicker than 8" on the bottom would be too much.

I have a trundle bed mattress. It is about an inch shorter than the front panel. A regular twin mattress should be OK. Measure the height.

There is slack of material on my bed, so it is not necessarily a tight fit on a regular height mattress. I have not had an issue of it slipping off my bed. Unless the protector is plastic that you would put this over, you should be fine.

Hi Kate. I am sorry that I do not have an answer for you. I am not familiar with extra long twin mattresses. Maybe you can contact the salespeople who are selling the product. Hopefully they will have an answer for you.

It fits a regular mattress, it you have a bigger one, I am not sure it would fit.

My mattress is 13" high and it fits very snugly - I'm really not sure how it would fit an 8". Sorry.
