The tan/blue sample blends with the fabric of your bed and your wallcolor and won't draw a lot of attention to itself. It will look like bound carpet. The trellis pattern will look more like an area rug. Right now your room is very neutral feeling with subtle touches of blue. The blue trellis will boost the blue factor in the room quite a bit. It would look great. If you think it will be too much blue for you, select the linen/ivory trellis. Then you will have versatility to change up the color scheme of the room in the future if the mood strikes you.

I did see the tent/fort covers online too. I like them also. Or I could maybe use a cool shower curtain. So it seems like nobody likes the round rug. This makes it hard because it was my husband's first choice. lol. The middle two have the advantage of being padded with memory foam to protect against accidents but they are the smallest and only 5 feet wide. I like the idea of two rugs which I didn't really consider before. I could do a solid color or coordinating pattern underneath just the Loft portion.

If you are considering buying any of the ones you posted, try and get the smallest size available because if it doesn’t work out, it will be much easier to return. Just remember to check the return policy and possible restocking fee.

What about one bigger rug? I think for your bedroom, it would look better and more cohesive: https://www.rugsusa.com/rugsusa/rugs/rugs-usa-handwoven-chaste/Natural/200HMMT01A-P.html
