Simple to assemble
This company gets a A+ on how well thought out the DIY assembly is. Easy to put together, SPARE screws and even a little ratchet allen wrench to make it even easier. Seriously if this is hard for you to assemble buy reassembled products.Vey thoughtful. There is velcro on the rails and on the straps holding the boards together. Very well thought out.The cover fits over everything and is held snug with an elastic cord. The bottom is open and exposed but that means air flows even easier.I used it (4 inch version) under a very tall hybrid foam mattress and was the perfect height on my bed. Slept on it one night (so far) and it was quiet and supportive on my mattress.
