Mattresses last an average of 8-10 years.

Cleaning a mattress is a simple step-by-step process. First, remove all bedding and covers to wash separately. Then, use the upholstery attachment on your vacuum cleaner to thoroughly vacuum the entire surface of the mattress, paying special attention to seams, crevices and edges. Then, spot-clean stains where needed using different solutions depending on the stain type. Once the mattress is clean, sprinkle a generous layer of baking soda over the surface to deodorize. After a few hours (ideally overnight), vacuum the mattress thoroughly to remove all residue.

Pocketed coils are designed to flex independently, so the mattress can respond more precisely to different parts of your body. In this Silver BRS900, the coil system is intended to provide support where it is needed while keeping the overall feel responsive.

It is designed to help. Because the coils move more independently, the mattress helps isolate motion between two sleepers, which can make it easier to stay settled when your partner shifts positions.

DualCool Technology is an antimicrobial performance layer designed to help keep the mattress feeling fresh. It also works to move heat and moisture away, supporting a cooler, more comfortable sleep temperature.

The gel memory foam lumbar layer is placed to add support and comfort in the lower-back area. It helps create a more supported feel through the middle of the mattress without changing the overall medium firm character.

Medium firm is a popular choice if you want a balanced feel that is not too soft and not overly firm. The Silver BRS900 can be a good fit for sleepers who want steady support, plus a touch of contouring comfort from foam layers on top.
