Description

Head, foot, and lumbar — the Best Base adjusts all three, which is the feature that separates it from nearly everything at its price. Add three programmable positions, anti-snore and zero-gravity presets, a built-in massage feature, wireless-connected speakers, and under-bed lighting, and the name stops sounding like bravado.

Sized Twin XL through California King on one listing, it is Sierra Sleep's answer to smart bases costing half again as much — the complete feature sheet at house-brand pricing.

Margate, Northfield, and Somers Point shoppers should demo the lumbar rise specifically at The Mattress Store inside our Northfield showroom; it is the feature the price makes surprising.

Questions & Answers

What does the Best Base adjust?

Head, foot, and lumbar independently — plus three programmable positions and anti-snore and zero-gravity presets on the remote.

What sizes and prices does it come in?

Pricing depends on the size you choose — select one above to see its price.

What extras are built in?

A massage feature, wireless-connected speakers, and under-bed lighting — the smart-base feature sheet, included rather than optional.

Which mattresses pair with it?

Memory foam, hybrid, and wrapped-coil builds — most current mattresses we carry. Ask our team to confirm yours.

How does it compare to premium-brand smart bases?

Feature for feature it plays in the same conversation at meaningfully lower spend — comparing them side by side at the showroom makes the case quickly.

Frequently Asked Questions

Why choose an adjustable base?

Head and foot elevation helps with reading, TV, snoring, and circulation — and most current mattresses we carry are compatible. Try one under your shortlisted mattress at our Northfield showroom.

Do you deliver to the Shore towns?

Yes — we deliver throughout South Jersey, from Atlantic City down to Cape May, including Ocean City, Avalon, and Wildwood. White-glove delivery is available (delivery fee applies), or you can pick up at the store.

Do you offer financing?

Yes — financing is available through the Synchrony HOME card. Ask our team about current offers.

What if I find a lower price somewhere else?

Kensington offers a price match guarantee — bring us the price and we'll take a look.

Can I see this before I buy?

You can see this piece or comparable pieces in our two-acre Northfield showroom at 200 Tilton Road — a 4th-generation family store serving South Jersey since 1912.
