We wanted to test out Helix mattresses after the reviews I read online, and this store is the only one that keeps them out on the floor on the west side of Houston. Saad did a great job of helping my husband and I narrow our choices down. He was very patient and answered all our questions on the differences and the manufacturing process. We ended up making the purchase since the store gave us additional items/discount.

I went to about 4-5 different mattress stores and I was between the Helix and another brand. Saad was the deciding factor and treated my wife and I like true customers and not just a commission check. As someone in Sales, I will say he was the perfect mix of real/down to earth and salesperson. I respect his professionalism. Would recommend him all day long.

Mattress on Demand in Katy has given us a great experience in a quality mattress as well as for our wallet. I was very impressed with the knowledge that Tony has for quality sleep.

Great to Work With

Larry at Mattress on Demand was great to work with. Very honest and showed us all options, regardless of budget. I honestly don’t know if there’s cheaper options and don’t care. This was our first stop and the service alone was enough to sell me. They even followed us home for delivery. Can’t beat that. Thanks for a great experience. Will definitely be back when the kids need a new mattress soon.

We recently purchased a new Helix hybrid mattress and adjustable base from Mattress on Demand in Katy, TX. We had a great experience with Saad assisting us in making our final selections after our extensive research. The experience was enjoyable with no pressure or hard sell tactics and we felt the price was fair. Once our purchase was complete, Mattress on Demand delivered and set-up our new bed and frame, showing us how to use the adjustable base and answered any of our questions. We would highly recommend them for your next mattress purchase.

I recently had the pleasure of visiting a small business mattress shop owned by Tony, and it was a fantastic experience from start to finish. The shop boasts a diverse selection of mattress brands, catering to a variety of preferences and budgets. What truly set the experience apart, though, was Tony’s exceptional knowledge and dedication to his craft.

Tony took the time to understand my needs and preferences, providing insightful recommendations without any pressure. His expertise in different mattress types and brands made it easy for me to find the perfect match. Thanks to his guidance, I am now enjoying a mattress that has significantly improved my sleep quality.

If you're in the market for a new mattress and value personalized service, I highly recommend visiting Tony’s shop. His commitment to customer satisfaction and his thorough understanding of the products make it a standout choice.
