Customer Reviews
Great value on coils
I was looking to upgrade my existing mattress and found their King Size Pocketed Coils. The price was really competitive, especially compared to other sites I checked. I also signed up for their newsletter and got a small discount which helped. The coils were well-packaged and arrived without any damage. Definitely felt like I got a good deal and it made a big difference in my old mattress's feel.
Always a good experience
Got another 3 inch Dunlop Latex Topper. It arrived quickly and was just as described. This is my third order from them, and the quality and service have been consistently great each time. Always happy with my purchases.
Good components, minor issue
I ordered a DIY Hybrid Mattress Kit and a Bamboo Mattress Cover. The components were high quality, especially the 8 inch Pocketed Coil Unit. Shipping took 6 days to get to my place in Florida, which was decent. My only small complaint is the Bamboo Mattress Cover felt a bit thinner than I expected for the price. Overall, it's a solid choice for building your own bed, but maybe double-check cover specs.

Hey, thinking about building my own mattress with parts from here. How long does shipping usually take, like to California?
wondering if they ever have sales? trying to get a full hybrid kit but that stuff adds up.
