I purchased 2 of the chairs for my workplace and I must say, I actually am quite impressed by how comfortable they are. Easy to assemble and have had zero problem with them.
The desk was slightly difficult to put together because it was just me and the drawers are slightly off (most likely due to me). But other than that, I'm absolutely in love with this desk. It's amazing and spacious and allows me to do might work and organize my documents. I sort of enjoy doing homework now that I have such a lovely workspace!
Its good to clean them as they occur, but if they had gone unnoticed for a while, and appear set, the instructions will tell you how you can give your patio floor an intensive cleaning treatment. It will take at least 24 hours to allow for setting and drying so don't walk on it. Foot pressure will distort the finished floor if you do.
But I do love mixing and matching, it adds so much interest to an ordinary chair. Lift the top flap of fabric up and place each strip right against the edges of the cushion with the paper side facing up. Iron the strips into place with an iron set to medium heat, following the manufacturer's directions for setting the adhesive.
