This isn't one of the regular or common gifts couples usually receive on the wedding. Personally, I find this breakfast-on-bed table as something nice to have. Since couples won't really put much attention buying this kind of furniture piece, this can go for a simple and useful gift. Though commonly used on sick days, breakfast or any meal on bed once in a while might just stir some sweetness and spice to the newleyweds considering they have such piece to use.
This might mean extra effort on your part but it's worth doing all the trouble because this gift will be very much appreciated. Simply get the couple's best or favorite picture together and if it's not available, separate pictures will do. Put it in a good portrait frame (can be bought or made to order) then gather signatures and well wishes from all important people of the couple. This kind of personal gift will be one their wedding treasures. Options like picture book / album of friends, families, co-workers, relatives with written greetings or video messages put in all together will be a good personal-made gift. 
It's nice to keep everything about your wedding where you can always just take a look and reminisce. A scrapbook is a nice gift because it can serve as an album also not only of pictures but cards and other tags & important wedding stuffs of the couple. Keepsakes are always the best! 
Getting married is quite expensive, therefore one of the best would be "monetary gift". Putting it in a card as money insert will be presentable enough and it can even serve as a souvenir from you to the newlyweds. Getting a good card that suits the couple will also give a higher value to whatever amount you'll give. It's not really how much you give, but how much effort you gave to attend and be part of the event. Gifts are somehow the ethical way of thanking and giving blessings to the newlyweds.
