  • Perfectly petite with the comforting embrace of curved lines.

    TRNK Collection upholstered seating combines our appreciation for elegant, yet practical design with the enduring qualities of American manufacturing. The 'Arc' series is among our most striking and sculptural, yet small-space friendly. The series boasts a perfectly pitched and padded tight back, allowing us to save on space without sacrificing comfort.

    The series features down-wrapped, high density foam seat cushions, a rock-solid CAD-engineered plywood frame and a contract-grade sinuous spring system.

    The entire TRNK Collection is available in a wide range of carefully-chosen upholstery options, including a number of 'Performance' fabrics treated with stain repellant finishes (Liquid rolls right off! It's actually quite incredible).

    Each piece is made-to-order in the USA by expert craftsmen using the highest quality materials and techniques.

    The bench I never received

    Unfortunately I have never received the bench because delivery requires a signature and the company UPS to which you entrusted the delivery arrived without warning and thus the bench remains at a UPS warehouse. I am Canadian and the bench was ordered for my second home in Stowe Vermont which I cannot get to because of the border closure due to COVID 19. I have attempted to get it rerouted to my caretakers home, but to no avail. It would be really great fa you the sellers could intervene on my behalf to get the damned thing delivered to my home WITHOUT A SIGNATURE JUST COMMUNICATE EXACTly what day
    Of course, I believe you are powerless since apparently you don’t even know that I never got it! YOU DID NOT FULFILL THE ORDER .


    Angle Chaise


    Love the Arc Sofa, comfortable and beautiful shape!

    Nothing short of Amazing

    This sofa is the star of the show in my living room. I purchased the Arc Sofa (90") in Clavicle and could not be more thrilled. The construction is top notch, commercial grade performance fabric will easily handle my two toddlers, and most of all the design of the sofa is unlike any other. TRNK's warranty and customer service where the cherry on top. You won't regret your purchase.

    about Arc Sofa
    We love this sofa so much. We put it in our daughter's nursery because we wanted to buy something that could be repurposed later on, and it looks modern and sleek. It provides tons of seating room and we've also had a few people sleep on it! It's comfortable, low profile, and elegant, and has held up well.
