Fantastic build. Super solid and durable wood material. Mattress is memory foam and it lays on a full wood slab (just like a Tempur-Pedic). It'll be a nice nights rest for back or side sleepers. Totally pay for the upgraded delivery service - it'll be worth every penny. Wish we had. It's delivered on its wood pallet. They secure it underneath with 8 screws. That was a challenge to get out ourselves. Then, it comes fully put together. It weighs a ton! We couldn't even move it the two of us with shoulder dollies. Awesome for first floor room - a nightmare for second floor. We actually had to disassemble it and take it up in 3 pieces upstairs. Not a convenient project I recommend to anyone.
