Sleep Innovations

Frequently asked questions

Everything readers ask about the Sleep Innovations range — and about how this catalogue works.

Choosing the right product

What is the difference between the Marley and Shiloh mattresses?

Marley is a 12-inch medium-firm mattress with cooling gel foam — the balanced choice for back and combination sleepers. Shiloh comes in 12" and 14" versions with a softer medium feel and deeper pressure relief, which side sleepers tend to prefer.

Should I buy a new mattress or just a topper?

If the mattress is structurally fine but feels too firm, too warm or slightly worn, a 2–4 inch topper is the cheaper fix. If it sags, creaks or is past 8–10 years old, a topper only masks the problem — go for a mattress.

Which topper thickness do I need?

2 inches adds gentle contouring, 3 inches noticeably changes the feel of a firm bed, and the 4-inch dual-layer models add a full pillow-top experience. Heavier sleepers generally get more benefit from 3–4 inches.

Which pillow suits side sleepers?

The Contour pillow is shaped specifically for side and back sleeping. The Customizable Comfort pillow is a safe bet if you are unsure — its layers adjust from soft to firm and change the loft.

Do memory foam products have an initial smell?

Compressed foam can have a mild scent when first unpacked. It is harmless and typically airs out within 24–72 hours in a ventilated room. All products here are made with certified foams.

Prices, buying and this site

Are the prices on this site current?

Prices and ratings are captured from the retailer’s listings and refreshed regularly. The exact, binding price is always the one shown at checkout — treat figures here as reliable orientation.

Do I buy directly on this site?

No. This is a catalogue, not a shop: every "Check price" button takes you to the retailer’s listing, where the purchase, payment, delivery and returns are handled.

Is this site run by Sleep Innovations?

No. This site is an independent catalogue and is not operated by the Sleep Innovations manufacturer. We link to the official listings and earn a commission on qualifying purchases, which never changes the price you pay.
