Natsukage Thicken Floor Mattress for Adults - Foldable Futon for Sleeping, Guest Bed, Camping - Twin Size

Great for guests and easy storage

I’ve slept on shikibutons for over a decade now and for the price, this one is actually fantastic. It fits on my existing tatami mat perfectly and its outer material is strangely soft (in a good way). Honestly, the only thing that would have made it better is if the sheet that came with it was a full 360 encasement. Instead it’s a fairly good quality (and also strangely soft) fitted sheet like what would be used on a regular mattress, the problem with this is that it causes the corners of the mattress to curl up and fold until the sheet just comes up. Not a huge deal as I have a few existing encasements already but if you plan on using the one that comes, plan ahead on how you are going to resolve this

As a floor mattress, it’s not comfortable. As a futon mattress, it did not fit my futon. The fitted velvet like sheet that comes with it makes its corners round, which looks bad. Tried to return it, but only given the option to exchange with two products I did not need.

There are many similar Japanese floor mattresses for sale on Amazon at this price point but I chose this brand for the extras: the coordinating fitted cover (made of soft velveteen material & washable); the two storage straps; the zippered storage/travel bag. I liked all the extras that you get with this mattress; however, the mattress itself is rather thin even after I let it plump to it actual size overnight (see pics). It's not quite the 4 inches advertised, especially once the fitted cover is placed on it, which squishes the mattresses into a slightly smaller shape. Overall, I'm ok with this purchase given the price point & the extras that came with it. Other brands of floor mattresses received similar complaints about their lack of plushness so it might just be the case with this particular type of floor mattress: they aren't futon mattresses.

We have 4 dogs, 3 are an xxl breed and one is considered a large breed. Works great as a doggie bed, will consider getting a second one so all pup dogs can have full spread out room.
