I stopped by Sleep Basil, looking for an organic mattress and I was blown away by the service and selection of natural latex mattresses they have. The showroom was nice and peaceful, Phil was educational and not-pushy at all. He spent a lot of time helping me find the right firmness as a stomach sleeper. I decided on the Ethos Organic mattress. It’s so comfy, I’ve slept so well, and it was literally half the price of the Avocado mattress I was looking at! You can’t go wrong here, the owners are great and it’s nice to support a local business who are great at what they do! Truly the best mattress store in Denver.

View on GoogleThe team at Sleep Basil was incredibly helpful in finding the perfect mattress for our almost two-year-old. They were super knowledgeable and made the whole process easy. We were especially impressed that they could order additional beds not even on the showroom floor. Excellent service and experience from start to finish!
View on GoogleWe love our Gel Grid mattress recently purchased at Sleep Basil. We were actually in the market for a Purple mattress and discovered SLEEP BASIL, where we learned they had Gel Grid with Purple technology. Only difference was price! We went for Sleep Basil and are extremely pleased and VERY comfortable! Thank you to the super friendly and accommodating staff over there! That’s always a plus!!
View on GoogleI had such a great experience at Sleep Basil! From the moment I walked in, the owners made me feel welcome and comfortable. They truly care about their customers and take the time to get to know what you’re looking for, instead of just trying to sell you something. What impressed me most was their knowledge. They didn’t just point out mattresses — they explained in detail the differences between them, which materials are best for different sleep styles, and what I should really pay attention to when choosing the right one. It made the process so much easier, and I felt confident in my decision.
