I have 2 twins that are raised to put stuff under them and my 5 & 6 year old granddaughters and they have no problem getting in or out of bed.

Will any of your occasional overnight adult guests be seniors? It can be hard on the knees for older people to get in and out of lower chairs and beds. Something to consider. Kids will grow up quickly and can climb up into a higher bed.

Thank you !!

Are you using a frame that needs a box spring or a platform that really decides the height.

You might want to consider a Twin XL bed or better yet a double bed if you're planning on adults using it, if you have the space.

I have a guest bedroom that will be mostly used for adults and the twin that I’m getting for my grandson will be for overflow. I don’t have the space in the room for the twin XL.. I think I’m going to order a 14” platform and try to find a decent 10” hybrid mattress. I’m going to make a headboard out of oak wood planks..hope it all turns out. Getting him into a bed of his own while he’s with me will be a huge step for him
