Estimated Delivery, Shipping Costs & Availability
Varieties Which Are Typically In-Stock
The Silhouette Boxspring is typically stocked in all sizes in our Alberta warehouses. The Optimus adjustable bed is cleverly packaged in a smaller carton that fits in most vehicles. For this reason, our stores often have this adjustable bed on hand for immediate pick up.
Please see the lead times below for situations when the Silhouette Boxspring is sold out in your desired size.Lead Times for Out-of-Stock & Special Orders
If the Silhouette Boxspring is sold out in your desired size, replenishment inventory is typically less than 6-8 weeks away as we continually have containers arriving to our Calgary distribution centre.

General Availability Advice
The Mattress & Sleep Company is a family owned and operated business based in Alberta, Canada. We specialize in high-quality bedding, bath and mattresses from Canada, Europe and the USA. Our vast selection makes it impossible to stock everything. For this reason, our website does not offer real-time inventory availability as many of our products are made to order.
Please read the availability details above as we do make an effort to draw attention to products which are typically in stock in our Calgary, Edmonton and Sherwood Park stores and warehouses.
For time-sensitive needs, please give us a call Toll-Free on 1 (877) 750-1212 or Send us a Message and we will be delighted to help.
